On Saturday, whilst rehearsing for her routine for ITV’s Dancing On Ice, Lisa Scott-Lee decided to take advantage of the fact that the studio was based in the same complex as the Big Brother house and set and tried to shout a hello to her former bandmate, Ian H Watkins.

She ran into trouble however when Big Bro security guards thought she was a crazed fan and almost phoned the policve.

A source told the Daily Star: “Lisa thought it was only a bit of harmless fun. She didn’t realise she was going to get into trouble.

“The security guards are under strict orders not to let anything affect the Big Brother house. They saw her as an intruder. Lisa was terrified she was going to get arrested and miss out on last night’s show.

“All she wanted to do was to go and give Ian a few comforting words after seeing him in tears on Celebrity Big Brother earlier in the week.

“She’s like his big sister but the security guards weren’t aware of who she was.

“Lisa was furious. But she was glad to get her skates on and get back to the Dancing On Ice studios.�
