Madonna takes up karate

Madonna has taken up karate.

The Queen of Pop was inspired to take up the ancient martial art by her husband, 'Lock Stock' director Guy Ritchie, who has a black belt in the Japanese sport.

The blonde singer, whose daughter Lourdes is also a karate fan, has reportedly hired a personal mentor, known as a sensei, to teach her the complex moves.

A source close to the star said: "Madonna has been really enjoying her classes. Guy is into karate and Madonna's daughter Lourdes has had classes. "

The singer is already so obsessed with the sport, she reportedly wants a karate theme in the video of her next single.

Madonna, who is working on the as-yet-untitled record, is said to be adding to the video's choreography as she learns new karate moves and chops.

Meanwhile, the mum-of-two has been approached to be the face of a new Kabbalah energy drink.

The star, who has been a disciple of the mystical Jewish faith for over five years, is said to be currently considering the offer.

A Kabbalah spokesperson said: "We are going after the Red Bull market but Kabbalah Energy Drink tastes better."
