A huge congratulations are in order for Kelly Clarkson! The first American Idol winner is now official off the market.

She took to twitter to let everyone the news. "I'M ENGAGED!!!!!" wrote the singer Saturday night. "I wanted y'all to know!! Happiest night of my life last night! I am so lucky and am with the greatest man ever."

Fiance Brandon Blackstock, who happens to be Reba McEnrite's step son, apparently did a fantastic job at getting the ring too. I'm sure all of you girls would appreciate this bit of sharing too. "Everyone has been asking about my engagement ring, so here it is :) It's a yellow canary diamond with diamonds around it and Brandon designed it with Johnathon Arndt!" she wrote.
