Ellen DeGeneres Finally Celebrates the Big 5-0

(andPOP) - Ellen DeGeneres was finally able to celebrate her 50th birthday Saturday on the Warner Bros. lot in Burbank—even though her birthday was back in January.

Celebrating with 600 guests or so, including newlyweds Mariah Carey and Nick Cannon, Tom Cruise, Katie Holmes, Lindsay Lohan, Jamie Foxx, Paris Hilton and Clive Davis, the blow-out carnival and casino-themed party included performer Pink and deejay Samantha Ronson. The comedian had to previously postpone her star-studded birthday bash because of the writers’ strike.

As of September 2003, Ellen hosts the popular Emmy Award-winning talk show “The Ellen DeGeneres Show.”
