Newly single Justin Timberlake partied with actresses Eva Longoria and Alyssa Milano into the early hours of Saturday morning while celebrating his mother's birthday. The pop superstar - who recently confirmed his split with his girlfriend of four years Cameron Diaz - attended the exclusive Jet nightclub at The Mirage in Las Vegas, Nevada with his mother Lynn Harless, who turned 45 on Friday.

Timberlake ensured Harless had the time of her life by keeping the champagne flowing, and even took to the mic to wish her a happy birthday, as she blew out the candles on her three-tiered cake, made by celebrity chef Jean-Philippe Maury.

Olivia Wilde, Timberlake's co-star in upcoming new movie Alpha Dog, also joined in the celebrations.
