“I like to dress up for Carl,” the music icon told E! News on Wednesday, per Vanity Fair. “Every day, I put on some makeup and fix my hair because I think, ‘Well, the whole world, I’m out here and everybody else sees me all dressed up, and I’m not going to just kind of go home and just flop on him.’

“Nobody wants to make out with a slouch! It’s important to me that I look as good as I can,” she added. “I think it kind of helps keep things spicy.”

“I thought, ‘Well, I’ll just go surprise my husband and just cook breakfast for him in my bunny suit,'” she dished.  “He got a kick out of it, and evidently a few other people did, too!”
