Now, it’s Simpson’s turn to fire away – and she’s doing it on The Oprah Winfrey Show. In an interview with Winfrey set to air Wednesday, Simpson sums up her reaction to what Mayer had to say with, one word: Disappointment.
“There’s nothing worse than being disappointed in somebody,” she says. Asked if she’s angry, she responds, “I’m not angry. I’m – well, I’m a little bit angry.”
What exactly is she angry about? “I don’t want people to know how I am in bed,” Simpson says. “I mean, I guess I could have been a lot worse.”
The pop star quips about the fallout from Mayer’s comments: “My phone is ringing off the hook, I have to say.”
On another sensitive topic – her weight – Simpson, 29, tells Winfrey she’s comfortable with her current shape. “I love my curves,” she says. “I’m not going to ever be size 0, and I don’t want to weigh 90 pounds.”
