Jessica Biel has officially become Jessica Timberlake! Though she married Justin Timberlake in October 2012, the '7th Heaven' actress finally changed her legal name, taking on her hubby's.

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

As for what will appear on marquees, you can still expect the starlet to be known professionally as "Jessica Biel."

"It's weird because it's feels like almost nothing has changed," Biel has said about her marriage to the Holylwood Renaissance man. "But yet something that you really can't describe -- or something that isn't really tangible -- has changed."

Timberlake is equally thrilled to be tied down to the 'Illusionist' beauty.

"It's nice to marry your best friend. It suits me," Timberlake gushed to Ellen DeGeneres back in April. "Every once in a while I can catch a glimpse of her when she doesn't see me looking, and I have this moment where I'm like, 'If you never make a good decision...if you only make bad decisions for the rest of your life. You made one really good decision.'"

Here's hoping she feels the same way about changing her name!
