Terri Seymour Simon Cowell hollywood birthday sur ex-girlfriend pregnant

Wonder what baby mama Lauren Silverman thinks of this?! Weren't these two going out for a romantic dinner date just last week?

Simon Cowell celebrated his 54th birthday at Sur last night, and not only was ex-girlfriend Terri Seymour by his side most of the evening, but when the duo left the restaurant, she sat in his lap in the car! We know Simon's friendly with his exes but this seems more than just platonic if you ask us!

Silverman was not present for the celebration, but last month during a chat with Ryan Seacrest, Simon said, "Let's put it this way, I wouldn't expect her to be a single mother." Just about everyone interpreted that as the music mogul's way of saying he was going to put a ring on it, but maybe he just meant he was going to pay a ton of child support and get his flirt on with whomever he chooses? Whatever makes him happy! And clearly he's doing just that...
