A happy Valentine's Day indeed!

Christina Aguilera and Matt Rutler confirmed their engagement on Twitter on Friday, and the 33-year-old singer added a shot of her beautiful diamond ring and wrote, "He asked and I said" Of course she said yes ... that rock is stunning! "They're very much in love and are really excited to take this next step!" a source close to the pair tells People.

Aguilera and Rutler met on the set of her 2010 film Burlesque, and prior to that she was married to music producer Jordan Bratman from November 2005 until October 2010. Interestingly enough, Aguilera and Bratman finalized their divorce on Valentine's Day in 2011.

Check out her ring! And where are they? Looks like Hawaii...
