Arriving at the Chopard 150th anniversary party in Cannes this week, Paris Hilton looked stunning in a flowing strapless blue Alberto Makali dress.

But as she moved on the nightclubs of the French Riviera, the socialite soon realised perhaps a floor-length gown wasn't quite suitable for a night on the dancefloor.

As she danced on stage at the VIP Room club on Monday night, the 29-year-old narrowly avoiding exposing her cleavage to the revellers as gravity took hold.

The hotel heiress was clearly insecure about her low-cut dress as she was spotted repeatedly checking her 32B breasts hadn't spilled out of the dress.

Her over-exposure didn't stop there, the reality TV star later ended up flashing her backside as she lifted up her floor-length gown as she walked across the stage.

Her near-miss comes exactly a year after Hilton put on a very public show of affection with ex-boyfriend Doug Reinhardt in Cannes, who she split from last month.

The Simple Life star was photographed grabbing her breasts, lifting up her skirt and straddled Reinhardt while kissing him in front of stunned revellers at the very same nightclub.

Ahead of her wardrobe malfunction, Hilton started the night off at the Chopard 150th Anniversary party at the Palm Beach Hotel, where she mingled with the likes of Lindsay Lohan, Naomi Campbell and Kate Beckinsale.

The night was a real family affair for Hilton, who is holidaying on the French Riviera with her parents Rick and Kathy and younger siblings Nicky, 26, and Barron, 20.

But then she moved on to the after-party at the VIP Room with Nicky and Barron, where they were entertained by Lionel Richie - father of Paris's former best friend Nicole Richie.

Writing on her Twitter page, Hilton said: 'Had so much fun last night at the Chopard Party. Lionel Richie performed and was amazing! Love him.'

As well as the designer dress, the socialite was also wearing a pair of huge diamond earrings, which she revealed were a gift from a 'secret admirer'.

She gushed: 'The most beautiful earrings on Earth and the most incredible watch.'

Her friend Lady Victoria Hervey said Hilton was on a 'manhunt' in Cannes since splitting from Reinhardt after a 12 month on/off relationship.

Hervey said: 'She’s on a rampage to find a new hot, rich fella.'

English socialite Hervey found she was also struggling with her low neckline at the Chopard party as she adjusted her loose-fitting dress on the red carpet.

Hilton is currently staying with her family on a yacht docked in Cannes after flying in via private jet last Thursday.

She's already hit several parties and events, including the Monaco Grand Prix on Sunday and last night's World Music Awards.

She wrote on her Twitter page: 'Cannes is Amazing! We have the most incredible yacht and I'm with the people I love most! My friends and family.

'So much fun here! I love Europe.'
