Britney Spears' ex keen to earn his own money

Kevin Federline plans to release a fitness DVD so he can pay to put his sons through school.

The former backing dancer won full custody of Jayden James, 21-months, and Sean Preston, 2, last week.

So Kev, 30, whose weight has ballooned over the last year, is keen to make some cash.

‘I plan to get back to looking ripped again,’ he tells the Daily Star.

‘I know I have let it all go, but watch me fly this year.’

Kevin, who was married to Britney Spears, 26, for two years, hopes to release the tape in January.
