Jessica Simpson returned to the television after 15 years to do a duet on American Idol and tease her new music.

The singer delivered her first TV performance in 15 years during the season finale of “American Idol” on May 18. She sang her new track “Blame Me,” before teaming with one of this season’s “Idol” contestants, Josh King, on “These Boots Are Made for Walkin’,” which she recorded in 2005. That song, of course, is a cover of Nancy Sinatra’s 1966 hit.
