Howard Stern is adding his voice to the very public, very messy back-and-forth betweenKelly Clarkson andClive Davis. The radio shock jock, who is known more often for slamming celebrities than defending them, took a surprisingly sympathetic stance toward the American Idol alum's accusations that Davis had "bullied" her during their collaborations -- and mischaracterized her in his memoir, The Soundtrack of My Life. "I always find it sickening when management guys like to set the record straight about how f--king creative and what geniuses they are," Stern said on his show on Wednesday, Feb. 20. "And, like, this guy's trying to diminish what she does? Doesn't he have enough in life? Can't he sort of tell his story without f--king degrading her and putting her down?"

"First, he says I burst into 'hysterical sobbing' in his office when he demanded 'Since U Been Gone' be on my album. Not true at all," she wrote of her 2004 album Breakaway. "I cried because he hated ["Because of You"] and told me verbatim that I was a 's--tty writer who should be grateful for the gifts that he bestows upon me.'"

PHOTOS: Kelly's funny night at the Grammys 2013 "As anyone who has read The Soundtrack of My Life knows, I think Kelly Clarkson is a tremendous vocal talent and performer," he wrote on Twitter one day later, on Wednesday, Feb. 20. "In the book, I provide an in-depth look at our years together during which we shared major multi-platinum success, as well as a few creative differences. I am truly very sorry that she has decided to take issue with what I know to be an accurate depiction of our time together." Stern's comments Wednesday similarly praised Clarkson's vocal prowess, though he too saw Davis' memoir as a knock on the "Stronger" singer's talents.

"I don't understand Clive Davis' motivation for knocking this chick down." The 59-year-old radio host is no stranger to controversy himself, having come under fire earlier this year after calling Girls creator Lena Dunham a "little fat girl" and likening the HBO show's sex scenes to "rape" -- he offered Dunham an on-air apology a few days later. "It makes me feel bad, and I think she is getting the impression that I somehow think she's just a talentless little fat chick," he said.
