British television personality Simon Cowell hinted Tuesday he plans to marry his pregnant girlfriend Lauren Silverman. \"I genuinely never thought [fatherhood] was going to happen,\" Cowell, 53, told Ryan Seacrest on his radio show. \"Partly because I was scared of who I was going to have kids with ... . [But] Lauren and I get along really well and once I got used to the idea I thought, \'I think this is going to be very good.\'\" So, will he and Silverman, 36, ever tie the knot? \"Let\'s put it this way, I wouldn\'t expect her to be a single mother,\" Cowell told Seacrest. News of Silverman\'s pregnancy was reported this past summer before she was officially divorced from Cowell\'s friend Andrew Silverman, with whom she has a young son. The Silvermans have since agreed on settlement terms.
