Donald Faison - Donald Faison Engaged To Cacee Cobb

The Clueless star and Cobb, who worked as Jessica Simpson's assistant during her TV show Newlyweds: Nick and Jessica, have been dating since 2006 - and now Faison has popped the question.

The actor revealed the news by cryptically posting a message on Cobb's Twitter.com page quoting a Beyonce song, writing: "If you like it, then you better put a ring on it."

Cobb then replied, "If she likes it, then she better say Yes!"

And the stars' pals have already rushed to congratulate the pair on their happy news.

Simpson posted a picture of Cobb showing off her engagement ring on Twitter.com, alongside the words, "Congratulations, Cacee! I love you and your man!"

Faison's Scrubs co-star Zach Braff writes, "Congratulations to Donald and CaCee on their engagement. Just wish I was there to run around you both with sparklers."

Faison has three children from his marriage to Lisa Askey, as well as a son from a previous relationship.
