Howie Mandel and Bill Burr are caught in what appears to be a feud after Mandel surprised Burr on his podcast.

Bill Burr said he did not appreciate Howie Mandel surprising him with Billy Corgan after the guitarist suggested they could be half-brothers.

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.

In a new interview, Bill Burr candidly condemned Mandel's ambush; and the 'America's Got Talent' host retaliated with an edited photo of Burr and Corgan.

During a Monday appearance on "The Rich Eisen Show," the comedian, 56, slammed Mandel for surprising him with Billy Corgan during a recent podcast interview. Mandel framed the ambush as a family reunion, as the Smashing Pumpkins frontman previously theorized that Burr might be his half-brother.

Bill Burr says he 'didn't appreciate' being ambushed with Billy Corgan on Howie Mandel's podcast: 'Howie did what he did because he is a Hollywood whore and he doesn't care what happens.'

Howie Mandel has a deal — or no deal — for Bill Burr. It seems that as long as Burr continues to voice his disappointment towards the comedian, the “America’s Got Talent” judge will continue to poke fun.
