Gwyneth Paltrow is busy promoting her latest eat-nothing-but-kale-and-juice cookbook or whatever, and she's gifted us with even more soundbites.

While her husband, Coldplay frontman Chris Martin, likes to cook in silence, Paltrow blasts the tunes. "He can’t have background music on: it has to be 100% of his attention. But if he isn’t at home, I turn on the hip-hop—I’m like a bad mutha rapping along to every word as I cook," she said.

All those moves and her diet (which, if the cookbook is any indication, cuts out dairy, eggs, wheat, soy, processed foods, alcohol, and basically everything good) must be working, though, because apparently her friends say the mother of two has the butt of a 22-year-old stripper. 

"I said, 'You know, this isn't so bad for 40, right?' And [my friend] goes, 'It's not so bad for a 22-year-old stripper!'" she said. She also does the "Tracey Anderson method" to stay in shape. 

We're still wondering what her favorite rap songs are. Care to venture a guess?
