Oscar winning actress Gwyneth Paltrow has revealed that she likes to rap and play hip hop music when she is cooking.

Speaking at the release of her second cook book, It's All Good: Delicious, Easy Recipes That Will Make You Look Good and Feel Great, The Iron Man actress admitted that she raps like a “bad mutha” when she is home alone.

Speaking about the different approaches she and her husband Chris Martin have to cooking Paltrow said: "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."

The 40-year-old also confessed that she "used" to diet ahead of red carpet events, but now focuses on living a balanced lifestyle.

"I've been doing the Tracey Anderson [diet and fitness] method for such a long time, and she's changed my body so much. I do have alcohol, French fries and ice cream, but I balance it out with exercise."
