After ambushing Bill Burr and Billy Corgan with a face-to-face meeting between the suspected half-brothers, Howie Mandel apologizes: 'I feel horrible'

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.

It all started when Burr appeared as a guest on Mandel’s podcast, Howie Mandel Does Stuff. In the middle of Burr’s interview, Mandel surprised him by bringing out Smashing Pumpkins frontman Billy Corgan. Back in November, Corgan told Mandel on the same podcast that, years ago, his mother confided in him that Burr might be his half-brother.

Howie Mandel said he feels "horrible" about angering Bill Burr by surprising him with his possible half-brother, Billy Corgan, in an interview.
