In November, Billy Corgan revealed Burr might be his half-brother while on the “Howie Mandel Does Stuff” podcast. Earlier this month, Mandel then secretly brought on the Smashing Pumpkins frontman during Burr’s interview. Burr shared he was not a fan of how the meet and greet went down.

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 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.'

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.
