David and Victoria Beckham rap to baby bump

David and Victoria Beckham have been rapping to their unborn baby.

The footballer and his singer-turned-fashion designer wife are currently expecting their fourth child and the pair - along with their sons Brooklyn, 11, Romeo, eight, and five-year-old Cruz - have come up with a unique way of bonding with the forthcoming addition to their family.

A friend told Reveal magazine: "David's been rapping to the bump. His current favourites are Snoop Dogg and 50 Cent.

"Sometimes Victoria and their boys join in too which cheers her up and has them all in fits of laughter."

David, 35, is said to be making an extra effort to ensure 36-year-old Victoria's fourth pregnancy goes well and has vowed to spend as much time at home with her as possible.

The source added: "David has promised to stay closer to home for this pregnancy, he wants Victoria to be comfortable and is determined to keep an eye on her."

David has been interested in rap music for some time and Snoop Dogg, who filmed an advert for Adidas with the sportsman, has previously revealed he was teaching the soccer star some of his own skills.

The musician - who has three kids with wife Shante - said: "Beckham and I go way back. He's like a brother. I'm gonna show him to rap, for shizzle. He's my boy. He was terrific with my kids and they had a great time as he taught them how to shoot and score the perfect goal."
