Britney Spears, getting back into shapeBritney Spears has reportedly hired two nannies to look after her sons so she can concentrate on getting back into shape.

According to TMZ, Britney, who gave birth to second son Sutton last month, is in the gym “for hours at a time”, trying to loose her pregnancy-weight ahead of husband Kevin Federline’s album release party at the end of the month.

A source told the website: “she really wants to make a huge splash at Kevin’s release party and she totally wants to outshine Kevin and announce to the world that she’s back.”
