Britney Spears Has A New Best Friend
Britney Spears and Louis Walsh are "BBFs" since meeting on 'The X Factor' recently.

The judge got to swap from the UK to the US version of the talent show the last week standing in for head judge Simon Cowell - who was taken ill - and got on so well with new judge Britney they are now Best Friends Forever (BFFs).

Sinitta, a long time friend of both Louis and Simon, told Heatworld.com: "Louis is absolutely besotted with Britney. I called him the other day and it's all he talked about. They're new BFFs, and they're in contact with each other a lot!"

When they were recently interviewed, Louis admitted: "Britney and I are bonding."

The 30-year-old 'Toxic' singer added: "I have so much fun with him."

The other judges on the US panel also took to Louis, with Demi Lovato saying: "There is only one Simon...but Louis killed it."

Fourth judge, L.A. Reid, who butted heads with the Irishman over one contestant, held no grudges, saying: "I absolutely love working with Louis.I find him fascinatingly quick, thorough, and remarkably entertaining."

Although Louis was a hit on the show, it looks like his appearance will be a one off, as Simon is set to return at the San Francisco auditions tomorrow.
