While some years are added onto Federline’s age thanks to his dancing and for not being a "shallow mother[bleep]", more years were lost for abandoning his pregnant girlfriend, and mother of his two eldest kids, Shar Jackson for Britney.

In other news, Kevin Federline is giving away the sneakers he wore during his debut music performance at the Teen Choice Awards to one lucky fan.
The aspiring rapper, the husband of Britney Spears, was panned by critics for his rendition of his new single 'Lose Control'.
Now any fan who pre-orders a copy of his debut album on the internet will be entered into a draw to win the autographed pair of sneakers.
But they are only second prize. The grand prize is a trip for two to Los Angeles for two nights and three days, and VIP invites to Kevin's Halloween album release party, which will be attended by Kevin and his wife Britney.
Ten runners up, all chosen at random, will win a replica of the Federation Medallion which Kevin's personal website claims he wears "almost every day".
The first 500 fans to order the album will automatically win an autographed photo of the fledgling rap star.
Last week, Britney gave birth to the couple's second son - Kevin's fourth child - who they have named Sutton Pierce. The tot shares the same initials as his older brother, Sean Preston.
Meanwhile, Kevin is due to make his acting debut in hit US series 'CSI' and is preparing for his promotional album tour which starts in October.
