Matt Rutler gave girlfriend Christina Aguilera the best Valentine’s Day present a girl could ask for: An engagement ring!

The Dirrty singer accepted and took to her Twitter page to showcase her new rock—captioning the photo simply, “He asked and I said…”

This will be Xtina's second marriage—she was previously wed to producer Jordan Bratman from 2005-2010 and actually met Rutler on the set of the film Burlesque, just one month after she split from Bratman.

In short, she was with Brat, met Matt, divorced Brat.

Bratman and The Voice coach share custody of their six-year old son, Max.

"Matt and Max are crazy about each other. Matt is a real natural with kids," a source tells Popdust exclusively.

For now, the couple is shacked up in Christina's $10 million Los Angeles mansion.
