Paris Hilton dating 'Hangover' director Todd Phillips?

Paris Hilton has been snapped by photographers while on a possible date with Hangover Part II director Todd Phillips.

Hilton and Phillips are believed to have spent an evening at LA's famed Chateau Marmont hotel this week, and later met the socialite's sister Nicky at the Beacher's Madhouse nightclub in the Hollywood Roosevelt Hotel.

The pair displayed their affection for one another throughout the night, even openly kissing at several points, a source disclosed to People.

After spending a few hours at Beacher's Madhouse, photographers spotted the pair leaving together in Phillips's car.

Reps for Phillips and Hilton have yet to confirm or deny whether the two are romantically involved.

The World According To Paris star recently professed that she planned to stay single for some time following the end of her relationship with former boyfriend Cy Waits.

Earlier this week, a man convicted of attempting to burgle Hilton's home was sentenced to two years in jail.

The World According To Paris airs Wednesdays on Oxygen.
