Pop trio the Sugababes have become the latest stars to sit in the Big Brother: Celebrity Hijack chair.

And the girls had a surprise for the remaining housemates, when they actually sang live for them in the house on Sunday evening.

Suspicions had been aroused earlier in the day when a stage had appeared in the house - with the housemates suggesting that an eviction twist may be on the cards.

"If it's not an eviction, then what is it?" asked Nathan. However their questions were answered when the band took to the stage and performed their recent single About You Now.

"How's everyone doing?" they asked. "Better now," Anthony joked upon seeing the threesome - who admitted the impromptu gig felt a bit strange.

"That was bizarre for us," Heidi said afterwards.
