Rula joins Maggot and GLC on stage

Rula Lenska joined Maggot and his band Goldie Lookin Chain on stage for a gig in London.

The fellow Celebrity Big Brother stars performed together on finale song Your Mother's Got A Penis.

"He's brought one of his friends along, so we've got royalty in the house tonight," band member Dwain Xain announced to the crowd. "Give it up for Rula Lenska."

NME.com asked her if she had been shocked by the track's explicit lyrics. "I've done The Vagina Monologues on the road," she explained, "so nothing is exceptional."

She was surprised at Maggot's on-stage energy compared to his behaviour in the BB house. "What I loved was the raw committed energy. They played to the audience, not at the audience," she said. "I was amazed to see Maggot's physicality because we didn't see much of that in the house."
