Chery Cole @ her Promise Ring launch party

Where: Nobu, Park Lane
Joanne Black style: Azzaro dress, YSL heels, Sergio Rossi clutch and Stephen Webster earrings

As president, owner and founder of de Grisogono, Fawaz Gruosi certainly knows how to throw a party – as I discovered at the Cannes Film Festival earlier this year. So, when the opportunity came up to appear at the launch of Cheryl Cole’s Promise collection – of beautiful rose gold and blackened silver rings to be worn on the little finger – I just had to take it.

With everyone from Louis Walsh and Diana Vickers to Kimberley Walsh and Nicola Roberts on the guest list, you could be forgiven for thinking you’d walked into an X Factor after-party. Of course, Cheryl was the star of the show, dazzling guests with her stunning, short, sequined nude and gold Elie  Saab dress, which complemented her petite frame and skin tone perfectly. But, one my of personal highlights was chatting to the X Factor’s Irish judge.  I reminded Louis that we once judged a Miss Ireland competition together and he asked whether I’d ever considered singing! Let’s just say, I’ll don’t think you’ll be seeing me at next year’s auditions.

Sipping lychee and passion fruit martinis, I was able to soak up the rest of the style on show. Socialite Tamara Beckwith stepped out in a great dress with cream and black details on the front, which she wore with some very sexy tights. Girls Aloud’s Kimberley and Nicola both opted for fab short black dresses. But the stand out look of the night (after Cheryl) was Florence Welch of Florence and the Machine, who was wearing a short white crocheted vintage dress and looked every inch the rock star.

Power stations aren’t usually associated with lavish parties and tuxedos, but then Battersea Power Station is no ordinary power station. This cool venue was home to host Kevin Spacey, the great and the good of the theatrical world and the legendary Paul McCartney for one night only. And what a night it was…

Nights on the party circuit are typically spent admiring well-styled women and their fabulous outfits. But it was the men who shone through at this star-studded spectacular. Ronnie Corbett looked so cool in a fab electric blue velvet jacket with a black lapel. Evgeny Lebedev wore a great black and white tux-style jacket and trousers with a white stripe down the side. Mark Ronson also opted for a tux-style suit (which became the look of the night together with an open shirt and no bow tie). And Jeremy Irons looked effortless in brown leather biker boots, beige jeans, a navy jacket and cool aviator shades.

The men also gave us the stand-out performances of the night. Kevin Spacey delivered a hilarious speech (that man should be a politician) and Paul McCartney had the celeb world falling at his fee, belting out tunes such as The Long and Winding Road and Hey Jude, which he dedicated to Dame Judi – who was at the party with her daughter.

The Old Vic 192 Fundraiser – organised to raise money for the theatre trust and support Meat Free Monday – was a night full of surprises. From my table, I took part in the art auction and walked away with a fabulous picture by Sam Taylor Wood. And a friend and massive McCartney fan who came with me was handed the singer’s plectrum – and will no doubt be envied for many years to come for securing such an amazing musical memento.

Joanne Black @ the Raisa Gorbachev Foundation Gala

Where: Hampton Court
Joanne Black Style: White dress with scooped neckline from Osman Spring/Summer 2010 white collection, YSL bag, shoes and jewellery

Walk the red carpet with a fashion designer and you’ll never want to walk it alone again. Arriving at the Raisa Gorbachev Foundation Gala on the Osman’s arm was a moment I will never forget. Sporting a red sash, he looked like a fabulous picador, and was certainly the best dressed man there. He described me as his muse for the night – and wearing a beautiful modern geisha-style creation from his spring/summer collection, I was definitely dressed for the part.

Hosting a table at the fifth annual Gala – a night dedicated to raising money for the Foundation and Marie Curie Cancer Care – gave me the perfect opportunity to both surround myself in fashionable people, and do a bit of style spotting. Among the highlights was Hugh Grant, the humorous commentator for the night. He looked effortlessly cool and ruggedly handsome in a suit with an open neck shirt. Anjelica Huston (who I consider to be a bit of an inspiration for everything she’s packed into her life) wore a lovely black and white dress and Tracey Emin put in a stylish appearance in Vivienne Westwood. And businesswoman Helen Davison went creative with a skirt crafted out of a Matthew Williamson dress and a handmade black lace top (I reckon she’ll be a designer to watch in future). But the coolest look of the night came from the ever-youthful Yasmin Le Bon, who stepped out in a trendy, dramatic fan-detail structured cocktail dress.

Raising nearly £2m for charity, the Gala was a huge success. I left Hampton Court that night a little lighter – having secured a three day apprenticeship with photographer Tony McGee and danced the night away to the sound of Bryan Ferry – and feeling better than ever. The dress was a huge hit and saw me receive more compliments than I ever thought possible. At a fitting with Osman (where I tried on three dresses from his white collection) he said the full-length number would be a winner with well-matched accessories – and he was right! Being told I had the best look of the night was great, but hearing that I’d managed to secure Osman a new following (and an order or two) by promoting his fabulous designs, was even better.

Where: Hotel du Cap

Joanne Black Style: White Jitrois leather dress, Lanvin sandals, Prada bag and De Beers diamonds

Put more than 400 stars of the screen – and international scene – together with fabulous food, a 20-minute firework display, dancers in catsuits and Cheryl Cole as guest of honour and what do you get? An unforgettable night out, that’s what!

This year’s de Grisogono Party, which was hosted by Fawaz Gruosi (who looked stylish in a stunning blue suit), was spectacular from start to finish. In style terms alone there was plenty to get excited about. Cheryl Cole stole the show on not one, but three occasions! First, she wowed us with her breath-taking Roberto Cavalli strapless black tulle gown and dazzling de Grisogono jewels. Then she delivered a great 30-minute set on stage, which included the song such as Stand Up. And finally, she gave us a look at her cute and daring side with a coral red twisted pleat georgette dress by Julian McDonald. What a woman!

Special mention also should be made of Naomi Campbell, who looked fantastic in a short white beaded L’Wren Scott dress and those dancers in red glitzy catsuits and black jackets (I was exhausted just looking at them dance away to Michael Jackson’s Smooth Criminal). Wow!

Joanne Black & Mira Anafina at the Chopard party

Where: VIP Room
Joanne Black Style: Nude Martin Margiela dress, Sharon Wauchob jacket, Bottega Venetta earrings, YSL clutch and Sergio Rossi shoes

What’s better than spending the evening sipping wine at a lavish star-studded party? Sipping wine at two lavish star-studded parties! When faced with Charles Finch spectacular and Chopard’s 150th anniversary party, there really is only one option – go to both.

Fashionistas and film festivals are a match made in heaven, and you only need look round the room at a Chopard party to find out why. Less was certainly more at this event. While Paris Hilton went long with a beautiful plunging royal blue gown, Eva Herzigova wore a super-short nude number, presenter for the evening Myleene Klass went strapless with a knee-length nude outfit and Lindsay Lohen wore a short snappy number with silver-coloured shoulder accessories. Marion Cotillard even opted for an edgy alternative to the full-length gown, stepping out in a glitzy jump suit.

This was, however, a night dedicated to more than just the well-styled and the stylish. Lionel Richie gave a show-stopping performance, belting out numbers such as a Dancing on the ceiling and Easy on a Sunday Morning, and Jesus Luz did a great turn as DJ, helping us dance the night away.
