The couple's happy news went public thanks to Faison's Scrubs co-star Zach Braff, who recently tweeted: "Congrats to @donald_faison and @caceecobb on their engagement. Just wish I was there to run around you both with sparklers."
Well, Cobb, 33, sure said "Yes!" to her longtime beau, 37, who will be walking down the aisle for his second time. Faison was previously married to Lisa Askey and has one child from the relationship.
For Cobb, this will be her first, though she knows a thing or two about marriage, having been Jessica Simpson's former assistant and appeared with the singer on MTV's Newlyweds.
