The former Friends star is engaged to be married to her fiance Justin Theroux. Jennifer is so in love with him that she plans to change her trademark "brand" last name to his.

A source told People Magazine, "She plans on privately changing her name to Theroux. She likes the way it sounds and joke that [Jennifer Theroux] sounds very posh. They really seem to have perfect chemistry, like they complete each other.

"There's a perfect balance. He was doting when she turned to him [at the Oscars], but the overall vibe was simply fun and effortless. [Jen] is crazy about Justin and can't wait to be his wife. Jen seems more confident than ever and they've become a great team."

The couple will allegedly get married after she finished her current movie project at the beginning of March. A source says, "It will be a small affair with their closest friends." Jennifer and Justin have even designed their own wedding bands to make their marriage more personal.
