Christina Aguilera engaged

Singer Christina Aguilera is engaged to her boyfriend Matt Rutler after he proposed to her on Valentine's Day. She said yes.

Rutler, a film producer, popped the question to her Friday. She accepted the proposal and later flaunted her huge new diamond ring via a photograph on microblogging site Twitter, reports contactmusic.com.

The post shows the picture of the couple holding hands with her new ring on display prominently.

She posted: "He asked and I said... (sic)"

A source close to the couple, who has been dating since 2010, told People.com: "They're very much in love and are really excited to take this next step."

Aguilera met Rutler on the set of "Burlesque" in which she starred and he was a film assistant. At that time, she was going through a painful split from her first husband Jordan Bratman.
