Kevin Federline's girlfriend Victoria Prince is treading on Britney Spears' toes by playing mum to her two sons, according to a new report.

The 6ft 2" blonde volleyball player - who has been dating Kevin for the last few weeks - has reportedly taken a shine to Jayden James and Sean Preston.

The couple were recently spotted eating lunch with the boys at a Japanese restaurant in Fresno - with Victoria apparently taking to the role of mum with ease.

A source told Life & Style: “She’s really smart and witty. She’s a strong and independent woman, and always wears the pants in her relationship.

"I hope Kevin can handle her! She’s pretty hard headed. She’s not afraid to speak her mind, even if it means insulting someone.”

Let's hope Britney, Victoria and K-Fed can all play happy families!
