Jessica Simpson performed live on 'American Idol' after a 15-year hiatus, her last TV appearance being a 2010 Rockefeller Christmas duet

The internet was buzzing after Jessica Simpson performed on the American Idol finale. Her first television performance in 15 years received mixed reviews from viewers, and Simpson opened up about how bad her nerves were before she stepped on stage.

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.
