Rosie O’Donnell sat down with her future boss and most power woman in the world, Oprah Winfrey for a revealing interview in O Magazine.

O’Donnell spoke her split with Kelli Carpenter, how she keeps her rage at bay and her new show on the OWN network.

First Rosie tackled her 2007 break up with Carpenter saying, “In the O’Donnell family, no one had ever been divorced.”

Apparently their lifestyles were just too different and eventually drove them apart.

“She wanted to play tennis at the country club, and I don’t do country clubs. I tried,” O’Donnell said. “They made an exception for a gay family, and we joined. It was a big thing: ‘They let in a gay family – whoo!’

O’Donnell also revealed to Winfrey that she has been receiving estrogen treatments that have helped her control her rage issues.

“I had, like, zero estrogen. And since I got some, I’ve been able to function more normally,” says O’Donnell. “I’ve stopped being so angry. You know, I think I had a lot more rage than I was aware of.”

Now O’Donnell will be returning to television with the debut of The Rosie Show on OWN next month.

Oprah praised Rosie by admitting, “in 25 years of doing my show, only one competitor ever seriously challenged me in the ratings: Rosie O’Donnell.

“From the day Rosie took her place among the crowded field of talk show hosts, I knew she had the ‘It’ thing,” Oprah explains.

And because I’m sure Oprah was waiting for it, Rosie returned the praise by revealing that she had dropped a deal with NBC to join Oprah’s television network.

Rosie proclaimed, “I was actually on the verge of signing a new deal with NBC, and — this probably sounds kiss-assy, but it’s true — just before I was about to sign, I remember saying to my agent, ‘Doesn’t Oprah have her own channel? Can we call there?’

“If I was going back to entertaining, I wanted to work with you.”
