Hotel heiress Paris Hilton was one of the stars in Vegas this weekend celebrating the grand opening of the new Fantasy Tower at The Palms Casino Resort.

Paris told 'EXTRA' about her luxury suite which features an indoor/outdoor infinity pool.

'Entourage' castmates Jeremy Piven and Kevin Connolly were in town for the party and to shoot scenes for an episode of their HBO series. Meanwhile, a grown-up looking Avril Lavigne enjoyed a little bowling before performing a split in front of the lively crowd.
