Well, that's one way to get back in touch with your ex.
Simon was seen arriving on the red carpet with his ex-fiancée Mezhgan Hussainy (below)!
Whoa! We hope his baby mama Lauren Silverman was okay with Simon sharing his glorious chest hair cleavage with his former flame, even just for an event!
Well, actually, make that two former flames, because Simon also ran into Terri Seymour, who had dated him for a number of years and was covering the event last night for Extra.
The X Factor and Extra and exes? We basically only need one letter to summarize this whole story: X!
While the two just shared an innocent kiss on the cheek, Simon was perhaps a little too hands on in his approach in their one-on-one session.
Then again, usually the normal behavior for running into your exes is to act as awkward as possible, so maybe Simon is just better than most at being friends with his past lovers!
