Valentine's Day came early for Christina Aguilera. The sexy pop singer became engaged Friday night to her longtime boyfriend, music executive Jordan Bratman, her rep confirmed to PEOPLE.
Aguilera, 23, and Bratman, 26, were on vacation when he popped the question. The two have been dating for more than two years.
Bratman presented Aguilera with a diamond ring designed by London-based jeweler Stephen Webster.
"Christina was very surprised," says a close friend of Aguilera's. "She's ecstatic."
