Jessica Biel becomes Jessica Timberlake

Jessica Biel has officially taken her husband Justin Timberlake's surname.

"It's all official!" a source told Life & Style. "The paperwork is done and she's now legally Jessica Timberlake."

The former "Seventh Heaven" star will reportedly keep her maiden name as her stage name.

A week after marrying the "Mirrors" singer, Biel revealed that she would take his name.

"It's weird because it's feels like almost nothing has changed," she's said about married life. "But yet something that you really can't describe -- or something that isn't really tangible -- has changed."

Mr. and Mrs. Timberlake married in October 2012 in a lavish ceremony at the Borgo Egnazia resort in southern Italy. The couple had been dating on and off for the previous five years.
