Britney Spears will no doubt be ecstatic to learn that Kevin Federline's new girlfriend has received the seal of approval from their two sons.

The singer's former husband has been seen out and about with volleyball star Victoria Prince in recent weeks, but has yet to comment on the blossoming romance.

However, another of his ex's – Shar Jackson - has weighed in to confirm that the dancer turned wannabe rapper is serious about his new lover - because he's already introduced her to his boys Sean Preston and Jayden James.

She tells HollyScoop, "I met her (Prince) once and she was really cool.
But that's as far as I want to get involved in that.

“But the kids have spent a little time with her and thought she was pretty cool. So that's all that matters, as long as they think she's cool."

A US tabloid recently reported that Britney - who is rumoured to have snapped up this new Californian pad -  was so jealous of K-Fed's latest relationship that she had instructed her sons to 'spy' on the new couple.
