Howie Mandel is sorry.

The “America’s Got Talent” judge has apologized to Bill Burr for surprising him in an interview by bringing out Billy Corgan, who may or may not be the comedian’s half-brother.

“I feel horrible,” Mandel said on the latest episode of his “Howie Mandel Does Stuff” podcast. “I’m sorry, Bill. I’m sorry, Billy. I only tried to do something good.”

Mandel said it had been a “hellish week” for him amid the backlash to the interview but maintained he “legitimately thought I was doing something nice” by bringing Corgan and Burr together.

He also revealed that he has “been texting” Burr since the podcast, but “he’s not answering me.”

“I texted him and said, ‘Good episode,'” Mandel said. “Didn’t answer. I said, ‘Is there anything I can do to follow up?’ No answer.”

During Burr’s January appearance on Mandel’s podcast, the “Deal or No Deal” host surprised him with a special guest: Corgan, who months earlier revealed on the show that it’s possible he and Burr share the same father. The Smashing Pumpkins guitarist said his stepmother told him that Burr “might be one of the children that your father sired in his days being a traveling musician,” adding that his father “did once tell me that I had a half-brother named Bill, who was born around the same time as me.”

Burr appeared unhappy as soon as Corgan came out to sit next to him, berating Mandel for the “rude” surprise, while Corgan expressed confusion that Burr wasn’t aware he would be coming.

“Can this be edited out, or no?” Burr asked, and he told Corgan, “Did you ever think the fact that I never told that story, that maybe you shouldn’t?”

Fans were initially unsure whether Burr was legitimately upset or if he, Corgan and Mandel were all doing a bit. But Burr subsequently appeared on “The Rich Eisen Show” and made clear that he really “did not appreciate what Howie did.” He slammed Mandel as a “Hollywood whore” and said he could have given him a heads-up beforehand.

On his Tuesday podcast, Mandel acknowledged he “hurt (Burr’s) feelings” and said that “if he feels bad, I feel bad.” He also told his guests, Randy Sklar and Jason Sklar, that if they “bump into Bill or Corgan, please tell them I’m sorry.”

At the end of the episode, Mandel reiterated, “A sincere apology to Bill and Billy. I didn’t mean anything. Please call me or check in with me. I am truly sorry.”
