Kelly Clarkson Is Engaged!

No longer 'Miss Independent,' the pop queen announces that she and boyfriend Brandon Blackstock are set to tie the knot.

Kelly Clarkson has yet another reason to celebrate this holiday season. Just a day before the "Miss Independent" singer is set to hit the stage in L.A. for "VH1 Divas," she announced to fans that she'll soon be Mrs. Blackstock.

"I'M ENGAGED!!!!! I wanted y'all to know!! Happiest night of my life last night!" Clarkson wrote in a tweet on Saturday evening (December 15). She went on to gush about boyfriend Brandon Blackstock: "I am so lucky and am with the greatest man ever."

The typically private Clarkson has been dating Blackstock for nearly a year, and back in June, she opened up to Redbook magazine about how she met the talent manager through his stepmom, country star Reba McEntire. The chart-topping 30-year-old, who has padded her catalog with breakup anthems, was so enamored of her BF, she admitted at the time that their relationship seemed almost too good to be true. "I told my assistant that today, I said, 'I'm just waiting for something to blow up.' "

Kelly Clarkson is just one of the pop superstars set to take the "VH1 Divas" stage on December 16!

Things continued to go well, however, for the couple. And during a heated election season, the Texas-raised, self-described "Obama girl," spoke to MTV News about how her supportive BF managed to be cordial and respectful even as he rooted for the president's opponent, Mitt Romney, during debates.

"We watched one [together]; it was pretty funny," she said. "We'd go back and forth. It's just funny, because usually couples like us would vote for the same person, but we're totally canceling each other out."

We don't know if she'll be rocking her new sparkler, but you can catch Kelly performing live on Sunday night when "VH1 Divas" airs at 9 p.m. ET.
