Betty White has to turn down invitation from Marine

Betty White has turned down the chance to be a Marine's date at an upcoming ball, because she'll be working.

Sgt. Ray Lewis became the latest military man to invite a celebrity as a date after asking the Golden Girls star to the Marine Corps Ball in November in a video posted online over the weekend.

But, unlike Mila Kunis and Justin Timberlake, who have accepted invited to attend seperate military events, White politely declined.

In a statement, the 89-year-old writes: "I am deeply flattered and truly appreciate the invitation. As everyone knows I love a man in uniform... but unfortunatel I cannot accept, as I will be taping an episode of Hot in Cleveland."

Mila Kunis and Justin Timberlake were in New York last night to attend the premiere of their new film, Friend with Benefits.
