Socialite Paris Hilton was spotted "flirting" with pop sensation Justin Bieber when they partied together at the ongoing 67th Cannes International Film Festival.

The socialite and the `Confident` singer are both currently in the South of France for the annual film festival and got close when she reportedly sat on the younger star's lap at Gotha nightclub, reports contactmusic.com.

An onlooker told the Daily Mirror newspaper: "Paris had a private table above the DJ setup at the nightclub and was clearly loving being out and being the centre of attention. She was trying to dance sexily and looked really up for a party."

Hilton is currently dating model River Viiperi.
