Kim Kardashian and Paris Hilton at P Diddy’s yacht party in Cannes

Paris Hilton had some hot competition in the form of her successor Kim Kardashian as they were both on board for P Diddy’s yacht party in Cannes last night.

It is not clear whether their paths crossed – but the two ladies were seen waltzing around in their respective glamorous ensembles.

Kim Kardashian poured her ample curves into a stunning lace outfit which consisted of a crop top and matching maxi skirt.

The two-piece outfit featured a beige slip and black lace overlay which included sequinned detailing.

The top had a sexy cut-out back and fell high enough for Kim Kardashian to flash her toned stomach.

Kim Kardashian swept her brunette tresses into an elegant ponytail and accessorized her outfit with black and silver chandelier earrings and a cute black bracelet.

Earlier, she attended the famous VIP Room club at the JW Marriott hotel to kick off her first evening at the Film Festival.

The skirt trailed along the floor as Kim walked the red carpet, giving a wave to her admirers at the same time.

Paris Hilton, meanwhile, opted for a demure floor-length deep pink dress, wearing her blonde locks on the Diddy boat party.

Paris Hilton, of course, is credited with teaching Kim Kardashian the ropes of the reality TV world.

They used to be firm friends back in the day – although their relationship has cooled over recent years.

Other celebs at the party tonight included Paris Hilton’s sister Nicky, Michelle Rodriguez, Adrien Brody and Tara Reid, who was spotted leaving at 4:00 a.m. looking a little worse for wear.

Earlier in the day Kim Kardashian was spotted in an all-black outfit but the French sunshine wasn’t enough to put a smile on her face.

However the reason behind her miserable mood may have been that she was forced to drag herself away from boyfriend Kanye West today to fly to Nice.

She left her man behind in London where he will play another show at the O2 London tonight with Jay-Z.

However the couple were later reunited and spotted walking arm in arm around the Cannes harbor at around 4:00 a.m. this morning after Kanye West jetted in.
