Simon Cowell was all smiles and jokes during his appearance on the Tonight Show With Chinny Leno. Simon said that he'll be getting married "in the next 10 years." His fiance Mezhgan Hussainy was also watching Simon in the background when Chinny Leno called her to the stage.

Mezhgan shared a seat with Simon as the American Idol judge looked so happy with her. Simon says that he's "torn" about having kids because he believes that he's "a bit too old to have kids." Uh Simon, that's why Mezhgan will be having them! Relax. We'd love to see little Simons around, too.

Simon also said that he loves Crystal Bowersox and that Adam Lambert should have won last year. Jay Leno sucked with his Idol trivia, only naming Jennifer Hudson and Adam Lambert as the more successful "losers" of the show. Um, hello, Chris Frickin' Daughtry is successful, JayJay!

On a sidenote: I love this couple!
