Congratulations are in order for pop superstar Christina Aguilera, who got engaged to her boyfriend of nearly 4 years on Valentine's Day. Xtina met Matthew Rutler on the set of Burlesque, who was working as a production assistant at the time, and the two are now happily calling one another their fiance. Proposing on February 14th, 2014, Rutler popped the question in a currently-unknown location, but Aguilera tweeted a photo with the caption "He asked and I said......" showcasing the couple's hands (with that crazy ring!) overlooking a tropical beach. Who knows where they could be — Mexico, Hawaii, even somewhere in California come to mind — but we're assuming they're happy! Since the engagement is so fresh, there are no wedding dates set by the couple as of yet.
