Is Christina Aguilera A Repeat Offender?

Christina Aguilera wasn't afraid to return to the scene of the crime.

The new Us Weekly reports that on March 4, three days after a wine-drenched feast at Osteria Mozza led to her public intoxication bust, the singer, 30, and her beau Matthew Rutler returned to the L.A. eatery.

On their menu that night? Two bottles of wine -- and absolutely no regrets.

"She acted as if the arrest never happened," a Mozza source tells Us. "When their server offered them dessert, they asked for more wine."

When it was time to leave, "She seemed tipsy," the observer notes. (Thankfully, the "You Lost Me" singer and her set assistant beau stayed safe this time, and went home via chauffeured limo.)

Still, an Aguilera insider notes that the star hasn't changed her hard-drinking habits since her brief, "welfare-related" arrest. "She should see the arrest as a wake-up call, but she doesn't. She doesn't think things are that bad."

Adds another source: "She's nearly fall-down wasted nearly every night."

Christina and BF -- Poppin' Bottles Before Arrest

Christina Aguilera and her boyfriend drank at least one -- possibly two -- bottles of expensive wine at a famous L.A. restaurant just hours before they were arrested ... TMZ has learned.

We've confirmed ... Aguilera and Matt Rutler had a late-night dinner date at Mario Batali's restaurant Osteria Mozza ... where they hung out in the private dining room past midnight.

We're told one of the restaurant patrons recognized Christina and asked the server to send her a drink ... but the server replied, "She's already drinking a bottle of wine... or two."

The patron sent over a dessert instead.

So far, no word on when Aguilera and her BF left the joint -- but sources who were at the restaurant tell us the couple got their entrees AFTER midnight ... when the place was closing down to the public.

As TMZ first reported, the couple was arrested around 2:45 AM this morning -- cops say Matt was driving drunk and Xtina was too drunk to take care of herself.
