More than a decade ago, Simon Cowell plucked Ryan Seacrest out of obscurity and gave him the opportunity of a lifetime: to host his new show American Idol. Needless to say, the series helped launch Seacrest’s multi-million dollar empire.

Despite no longer being on the American Idol judging panel, Cowell says that he still finds Seacrest “really annoying.” Of course, the judge’s playful banter with Seacrest helped make the Fox show must-see reality television — but after 10 years, is the shtick finally getting old? Not for Cowell, who couldn’t help but throw a few jabs at his former co-worker during Monday night’s Conan.

“You unleashed him and it’s your fault,” Conan O’Brien told Cowell. “I know. And the whole plan was to launch Brian Dunkleman,” Cowell responded, referencing Seacrest’s Season 1 co-host. “The whole thing failed.”

Who else did Cowell say was “annoying?”

The former American Idol judge said he’s used to working with people he finds annoying, including his fellow X Factor judge, Demi Lovato, who joined Cowell on Conan.

However, the 20-year-old pop star and former Disney starlet showed that she’s not intimidated by Cowell’s antics and responded,  “You can be a bit of an a**hole. How’s that?”

The X Factor airs Wednesdays and Thursdays at 8 PM ET on Fox.
