Paris Hilton apparently left Justin Bieber's party because he kept playing his own songs.

The 33-year-old hotel heir and Justin, 20, were both in Cannes at the weekend and were spotted partying at the city's Gotha nightclub.

It was reported that Paris even sat on the singer's lap at one point and that they left the club together to head back to Justin's house for a party.

Despite rumours the pair looked cosy, TMZ is now claiming 50 people attended Justin's bash and that Paris, who was apparently never alone with the star, left after just 30 minutes.

"She said the party was lame and couldn't stand the fact that Justin was playing his own songs... so she left after half an hour," the website writes.

It might not just be Justin's choice of music that prevented the blonde star from staying. Paris has been happily loved up with 22-year-old Spanish model River Viiperi since September 2012.

"I am so in love. I feel so lucky to have met him. He's one of the kindest, most loyal men I've ever met in my entire life, and he treats me like a princess," she previously gushed about her beau.

"He's the most beautiful man I've ever seen in my life."

Luckily it doesn't seem that Justin has been left disappointed by Paris' alleged disapproval of his party.

"All smiles (sic)," he optimistically posted on Twitter today.
