Mel B allegedly had a "massive meltdown" during a recent radio interview with Howard Stern.
The former Spice Girls star sat down for a chat with the shock jock to promote America's Got Talent with co-host Howie Mandel.
But according to The Sun on Sunday, Mel was miffed when she was asked about an alleged romp with former Playboy model Luann Lee.
The UK outlet reports Mel told Howie and Howard both to "shut up" before launching into a vitriolic rant.
"B***h, b***h, b***h," she allegedly then "screamed" when Howie asked her about a possible Spice Girls reunion.
"Isn't it always Victoria that says no? Didn't Posh swear off of it?" Howie was quoted asking.
Apparently Mel wasn't happy about the second line of questioning either.
She allegedly ordered: "Stop being a b***h. Don't believe everything you read — b***h. You are a big b***h."
Apparently the argument escalated further, with Howie even calling Mel a "c**t".
A spokesperson for the pop star had yet to comment on the report at press time.
Mel previous slammed radio host Howard after he blasted her casting on AGT, insisting she wasn't well-known enough to take on the job.
She brushed off the comments earlier this year, branding Howard "inappropriate".
In 2013, she also jokingly stormed out of another interview with the radio host, according to E! News.
The outlet reports Mel was upset when he asked her about her relationship with ex Eddie Murphy, with whom she shares a seven-year-old daughter.
"[Eddie's] a great guy," she said at the time. "I don't think I have much to say about him because I don't think it's appropriate. At the end of the day we have a beautiful daughter together."
