Kevin Federline to reveal all to Oprah

Kevin Federline is to lift the lid on his relationship with Britney Spears in an interview with Oprah Winfrey, a report has claimed.

The dancer is expected to talk to the chat show host early next year about the breakdown of his marriage and the couple's high-profile custody battle over sons Sean Preston, two, and one-year-old Jayden James.

A source close to Federline told the News of the World: "He wants to give his side and show the world he is a good father and concerned ex-husband. It's a huge step but he could turn around the public's view that he was the reason behind Britney's meltdown."

Federline has reportedly expressed fears that his former wife could kill herself because of her "wild" mood swings.

Spears and Federline split in November 2006 after two years of marriage.
