That's quite a diamond!

Kelly Clarkson, who announced her engagement to her manager's son, Brandon Blackstock, over the weekend on Twitter, publically debuted her massive canary yellow diamond ring at the VH1 Divas event, and Breaking Celebrity News has the photos.

Kelly, who showed off her ring on her Whosay page over the weekend after announcing the exciting news, was beaming from ear-to-ear at the star-studded event, as she flaunted the sparkler on her ring finger.

"Everyone has been asking about my engagement ring, so here it is," she blogged. "It's a yellow canary diamond with diamonds around it and Brandon designed it with Johnathon Arndt! They did an amazing job! I can't wait to make Brandon's ring with Johnathon as well!"

The American Idol alum, who started dating Blackstock, Reba McEntire's stepson, in 2011, performed Catch My Breath at the event.
