American Idol host Ryan Seacrest joined former judge Steven Tyler and Idol cohort Randy Jackson onstage for a spirited jam session with Aerosmith at the Chesapeake Energy Arena in Oklahoma City Thursday night.

"Ryan Seacrest is in the house!" exclaimed Tyler, who coaxed the 37-year old television producer, donning a very un-rocking Navy blue suit jacket -- on stage with the band and Jackson towards the end of their cover of The Beatles' iconic hit, "Come Together."

Jackson, who is used to big arena shows from his days as a member of Journey, looked perfectly at home onstage handling bass duties on the rock classic.

Both Idol fixtures were in town taping segments for the Fox series, which debuts in January. Aerosmiths's 15th studio album, Music From Another Dimension, came out Tuesday.
