Louis Walsh has hinted that Simon Cowell may marry Lauren Silverman, the mother of his unborn child.

Speaking at the launch of The X Factor ahead of the start of the series on Saturday night the Irish mogul said that Simon and Lauren were like “two teenagers dating”.

And he added that the 53-year-old could even rejoin the series in 2014 – if he was not too taken up with romance and fatherhood.

“He’s fantastic on the show because he makes everyone work hard,” Louis explained.

“But he’s got to fit in a baby now, and maybe getting married. Totally. I think it’s a possibility, I really do.”

Louis added that he thinks Simon “is going to be a great dad” – and that Lauren has transformed him.

“Lauren’s a great influence on his life – very positive and bubbly,” he revealed. “She seems to have got the fun back into his life.

“I love Lauren. I love all his girlfriends. He is what he is. I wouldn’t be here if it wasn’t for him.”

The X Factor kicks off on ITV1 on Saturday at 8pm, with a second show on Sunday evening at 8pm.
