Rosie O’Donnell isn’t one to shy away from controversial subjects and her radio interview with Andy Cohen this week was no different.

The star, 57, touched on Tom Cruise’s Scientology beliefs, her beef with Ramin Setoodeh’s book about “The View” and her relationships with Madonna and Whitney Houston.

On Wednesday’s episode of SiriusXM’s “Radio Andy”, O’Donnell gave an in-depth and well-rounded chat. A caller asked O’Donnell if Cruise’s Scientology revelations changed her opinion on the “Mission Impossible” actor. “It does make me worry about him and his life,” she confessed. That being said, the pair still regularly exchange gifts, “He’s really a classy dude.”

Variety‘s Ramin Setoodeh released a headline-grabbing book titled, Ladies Who Punch: The Explosive Inside Story of “The View”. O’Donnell agreed to interviews with Setoodeh about her co-stars and O’Donnell’s time on the talk show. She says she still regrets accepting to speak with Setoodeh.

“I was so angry with how [the author] promoted it,” O’Donnell told Cohen. “I shouldn’t have done it at all, I didn’t want to do it.” Particularly, O’Donnell took exception with how her experiences with child abuse were used to promote the book.

The entertainer also touched on her relationships with Houston and Madonna. “It was sad to see what was happening with her,” she said of Houston. Meanwhile, O’Donnell said there are lots of delicious foods at Madonna’s house but it is often served “very late.”

In April, it was announced O’Donnell would play Lisa Sheffer on the HBO television adaptation of Wally Lamb’s I Know This Much Is True.
