The housemates were stunned this evening when girl group the Sugababes sang live for them in the BB house.
Having been confined to the bedroom for hours, the housemates were baffled to find a stage erected in the living area.
Big Brother ordered the group to sit in front of the stage, generating much speculation among the remaining six.
"If it's not an eviction, then what is it?" asked a confused Nathan as John suggested that they might each be asked to make farewell speeches.
Anthony preferred not to get involved, explaining: "I'm not even going to speculate - I can't be arsed."
Soon all the housemates' questions were answered when the Sugababes emerged from the Diary Room and took to the stage.

"How's everyone doing?" the girls asked, as an amazed Anthony quipped: "Better now!"
Sugababe Heidi made the introductions before the trio launched into their recent hit 'About You Now'.
Once the song was finished, the housemates cheered exuberantly at the surprise gig.
"That was bizarre for us," admitted Heidi, though Keisha added: "We've had some weird gigs before, to be honest with you."
