Jessica Timberlake

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

Eleven months after marrying Justin Timberlake, Jessica Biel has officially taken her man's last name.

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

An insider close to the star says she'll still be known professionally as Jessica Biel.

A week after their Oct. 19, 2012, nuptials, the actress revealed she had plans to trade in Biel for Timberlake.

"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."

Justin and Jessica, 31, began dating in 2007. The pair separated in March 2011, but rekindled their romance that fall. The "Take Back the Night" singer proposed to the brunette beauty while vacationing in Jackson, Wyo., in December 2011.
