Kelly Clarkson is engaged. The "Since You've Been Gone" singer has announced she will wed 35-year-old talent manager Brandon Blackstock, who popped the question last night after nine months of dating.

The 30-year-old star - who shot to fame after winning American Idol in 2002 - shared her joy with her fans on Twitter, writing, "I'm engaged!!!! I wanted y'all to know!! Happiest night of my life last night! I am so lucky and am with the greatest man ever."

Kelly recently expressed her hopes that the couple would tie the knot even though they weren't yet engaged. Last month, she said, "We are totally going to get married. We love each other. We are totally going to get married one day. I mean, he's got to put a ring on at some point. But I'll wait it out."

Asked if she has thought about the kind of wedding she wants to have, the "Stronger" singer said, "Honestly I've never been the girl to plan a wedding. We will totally, probably elope."

Kelly previously called their relationship her "best accomplishment" after years of being unlucky in love: "I completely fell in love. I did! Welcome to Cheeseville! I don't know. Your priorities kind of shift and you become happier and all that stuff. It's probably my best accomplishment because I think, for me, especially, I just didn't think it would happen."
