Cake Boss Exclusive: Watch Regis Philbin Cause a Food Fight in Buddy's Bakery

One job Regis Philbin won't be doing after leaving Live with Regis and Kelly next month: decorating cakes.

The host dropped by Cake Boss star Buddy Valastro's bakery over the summer where he suited up in chef whites and got a free lesson in how to decorate a cake Carlo's style.

"You think that's so hard, Buddy?" Philbin said, as he attempted to smooth a layer of buttercream around the cake. "I sense that you're looking at this and you're very impressed, aren't you?"

Check out a preview of his visit below, and watch for when Buddy's cousin Anthony arrives — and the food fight that follows.

Philbin's last day on Live is Friday, Nov. 18. A new episode of Cake Boss airs Monday at 10/9c on TLC.
