Christina Aguilera is Engaged

Love is in the air.  After all, it is Valentine's Day. Christina Aguilera's boyfriend has popped the question.

Matt and Christina met on the set of "Burlesque" where he worked as a production assistant.  We're guessing he'll be getting a promotion soon.

Christina was previously married to Jordan Bratman and they have one child together, Max, who is 6 years old.
