Kevin Federline will "do anything" to get Britney Spears back.

According to reports, the wannabe rapper realises he has made a huge mistake and is desperate to win back his estranged wife.

A source told Britain's Grazia magazine: "Kevin spent last week begging Britney to take him back. Kevin is stunned and he's been crying. He said he would do anything to get Britney back. He knows he's nothing if he doesn't have her in his life and realises he has made a major mistake."

Kevin, 28, has reportedly tried a number of ways to convince Britney - who he has two children, sons Sean Preston and Jayden James, with - to rekindle their relationship, including singing her love poems and sending flowers.

The source added: "He sent flowers and chocolates to Britney, but she asked an assistant to put them somewhere where she wouldn't have to look at them.

He's also left voice messages, singing her love poems, but Britney hasn't replied."

Britney, 24, is believed to have instructed her staff to remove all of Kevin's belongings from their Malibu home and is enjoying having him and possessions out of her life.

The source said: "Britney says one of the perks of their break-up is getting her beautiful house back. His stuff was always messing everything up, littering the house with CDs, ashtrays, nicotine-smelling clothes and men's magazines.

"It has all been taken away now, there is no sign he ever lived there."
