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."
However, TMZ has reported that Paris is in denial mode. "We're told 50 people went back to Justin's house -- Paris was never alone with him. And something else we were told ... 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," TMZ reported.
Hilton is currently dating model River Viiperi (22).
