Louis Walsh opened up on his experience working with Britney Spears on the US version of The X Factor during Wednesday's (6 March) episode of Celebrity Big Brother.
The music manager, 71, worked with the singer, 42, for two days as a guest judge alongside Simon Cowell.
Describing what it was like being with Spears, Walsh told the housemates: "She was there, but she wasn't really there. She had earplugs in."
He added: "I love her, I love her music."
