Their relationship is blossoming along with her baby bump!

Simon Cowell and pregnant girlfriend Lauren Silverman grabbed dinner with DWTS judge Bruno Tonioli at Ago last night, and it's nice to see that the X-Factor head hauncho has ditched his harem of ladies in favor of being a one woman man!

In fact, we don't think it will be long before he pops the question!

"I wouldn't expect her to be a single mother," the British lothario recently admitted to Ryan Seacrest.

The music mogul has experienced a lot of surprises this past year, but he's taking it all in stride and looking forward to the future.

"I genuinely never thought [me being a Dad] was going to happen. 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,'' he added.

We can't wait for boy boy Cowell to make his big debut!
