Simon Cowell has reportedly proposed to his girlfriend of four and a half years, thirty-three year old Terri Seymour.

“American Idol” host Ryan Seacreast almost accidentally spilled the beans during the April 9th results show.

“At that point, Simon and Terri thought their engagement surprise had been spoiled by Ryan,” revealed an “Idol” insider.

“Only a handful of people at ‘Idol’ knew about the engagement, and Simon swore everyone to secrecy until he’d had a chance to break the big news first.”
