Big congrats to Kelly Clarkson and Brandon Blackstock, who got engaged last night (Dec. 14)! (See her engagement ring below.)

Announcing the happy news on Twitter, Kelly wrote just today, "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."

Just a few weeks ago, Kelly had opened up about her relationship with Brandon, an artist manager who's the son of Kelly's longtime manager Narvel Blackstock and the stepson of Reba McEntire. "We are totally going to get married," she predicted to Ellen DeGeneres.

It looks like Kelly's dream is coming true! Following the announcement, Kelly tweeted this picture of her new rock, a yellow canary diamond, with a white diamond perimeter, which her fiance designed with jeweler to the stars, Johnathon Arndt. "They did an amazing job! I can't wait to make Brandon's ring with Johnathon as well!" she wrote.

The happy couple started dating 10 months ago, but don't expect them to throw a big wedding, like good friends Blake Shelton and Miranda Lambert. "I've never been the girl to plan a wedding," Kelly also told Ellen DeGeneres. "We will probably elope."
