Britney Spears Celebrates Divorce in Las Vegas  4/3/07

Britney Spears spent her first weekend as a new divorcee in Las Vegas, dining with close friends.

The fallen pop superstar finalized her divorce from rapper Kevin Federline last week (ends30MAR07) and took off to Sin City for a low-key weekend.

The post-rehab Spears dined at Tao Asian Bistro on Saturday night (31MAR07) with two female friends, and made it clear her partying days are over - even in Las Vegas.

A fellow diner who spotted the party says, "Britney was dressed casual, wearing a light coat, hat and blonde wig. She and her friends ate vegetable dumplings, hot edamame, a California roll, and they split a wasabi filet.

"This wasn't a wild night out. Britney drank Pepsi and the girls were in and out in about an hour. Britney seemed very happy."
