Olivia Wilde & Jason Sudeikis

The 37-year-old actor is engaged to the stunning 'Rush' star and claims people must think he is blackmailing her because they believe she is too beautiful for him.

He told Maxim magazine: "You know, being beautiful is actually only like fifth or sixth of the things that are amazing about her. She's really hilarious. And she loves basketball!

"I think people look at us and wonder what kind of information I have on her to get so lucky. Like, I must have video of her taking a bomb into the White House."

Jason also hit out at the paparazzi, admitting it can be frustrating when they follow him and Olivia everywhere.

He said: “It is annoying when I want to go for a walk with my fiancee and there are three guys with cameras waiting outside my apartment. The biggest bummer is coming out of the ocean on vacation and seeing some photographer crouched behind a tree.”

Jason is preparing for the release of 'We're The Millers', his third movie with Jennifer Aniston and praised his co-star for being “vulnerable” and playing a stripper.

He said: “Playing a stripper in this one, she looks amazing. It’s such a vulnerable thing for somebody to do. I mean, I never take my shirt off even on 'Saturday Night Live'.
