SCOTS Big Brother poser Jason Cowan was kicked out of his favourite health club for streaking in the sauna.

The 30-year-old was booted out of the Healthland gym in Glasgow's Hope Street after fellow users complained about his frisky behaviour.

A former manager of the club said: 'Myself and a colleague had to ask him to leave.

'He was just having fun but some of the members were a bit put out.

'He tried to complain but I don't think anyone was interested.'

Adoption Jason, of Hamilton, Lanarkshire has not been seen at the gym since the incident 17 months ago. Healthland last night refused to comment.

The Sunday Mail can also reveal Jason's birth mum did not want to give him up for adoption.

Jane Astrauskas was forced to part with him when he was two years old.

His birth certificate shows he was born in Lanarkshire on November 1, 1973, to Jane. The space for his father's name is blank.

Friends of Lithuanian-born Jane said she always hoped Jason would find her.

A close family friend said: 'Jane has never forgotten her son and wants to tell him why she had to give him up. She wanted to make contact with him ever since she lost him when he was a wee boy.

'Seeing him on TV came as a major shock but she thinks he is beautiful and is very proud of him she never stopped loving him.

'Jane is a lovely person with a brilliant family.

'She has never made any secret of the fact she had a son who she had to give up for adoption.

'She hasn't been very well recently and meeting Jason would be a dream come true.'

The Sunday Mail revealed last week that Jane who has never married was the Big Brother housemate's real mum. Last week, Jane watched in amazement as Jason who claims to have bedded 250 women entered the Big Brother house wearing only a leopard-print thong and bow tie.
