Howie Mandel apologized for ambushing Bill Burr and Billy Corgan in the midst of their alleged half-brother drama. “I want to apologize. I feel horrible,” the “Deal or No Deal” host, 69, said on his “Howie Mandel Does Stuff” podcast on Tuesday.

Bill Burr isn’t happy with Howie Mandel. After appearing on “ Howie Mandel Does Stuff ” podcast, the “Old Dads” actor, 56, doubled down on his disappointment over being blindsided when Mandel, 69, ambushed his interview by bringing out the Smashing Pumpkins frontman Billy Corgan, 57, who revealed he might be Burr’s half-brother.

The actor and comedian made a recent appearance on an episode of the Howie Mandel Does Stuff podcast, where the host surprised him with Billy Corgan, the Smashing Pumpkins guitarist who previously revealed that the pair might be related.
