Roache, who plays Ken Barlow, made the revelations during an episode of Piers Morgan's Life Stories earlier this year.

"I'll have a go. I'll see if I can beat him," Thomas told The People. "Bill is a god. He's even more godly since he announced he has slept with 1,000 women.
"He is an absolute legend. Bill is so cool, such a cool guy. And nobody can say a bad word about him. He doesn't exploit it at all. It wasn't done in a seedy way.
"When the news came out, my friend Kelvin Fletcher from Emmerdale called me up and said, 'Ryan, can you get me Bill Roache's number. I want to go out for a drink with him'. I thought it was hilarious."
Thomas split from former co-star Tina O'Brien in 2009. The couple have a 3-year-old daughter named Scarlett.
"I'm not thinking about settling down," Thomas added. "I'm nearly 28. I'm having a good time and that's what it's all about. Going out is all part and parcel of being a young lad. We all like a good party, myself included.
"When I'm in nightclubs, girls do throw themselves at me but it's all done in good taste. The majority of them are quite respectful. I'm quite lucky. I get some good girls. I'm not silly with it though and know what I'm doing. I have some good people around me."
The actor, who plays Jason Grimshaw, confirmed that he is in talks for a new contract and has no immediate plans to leave Coronation Street.
"The storylines are great," he said. "I think I'm in Corrie for the long haul. The storylines I have been doing with Sue (Cleaver, who plays Eileen) lately have been amazing. She blows me away. She is absolutely incredible."
