Chmerkovskiy popped the question to his girlfriend of less than six months in Las Vegas on New Year's Eve, according to a source. The couple rang in 2009 at the Wynn Hotel in Sin City.
"They are really cute together," adds the source.
The couple, who have been dating since the summer, are currently performing on the Dancing with the Stars winter tour, which wraps up in mid-February.
Reps for the couple declined to comment.
The eighth season of DWTS kicks off March 9 on ABC.
