TLC has been announced as one of the exclusive guest performers at the season 21 finale of ‘American Idol‘ this year.

‘American Idol’ judges Katy Perry, Lionel Richie and Luke Bryan will also be taking the stage on finale night with each performing a song on stage. This season’s Top 12 contestants will also be returning to the Idol stage.

Katy Perry is a huge fan of TLC. She was one of the top contributors to the Kickstarter campaign back in 2015 and bagged herself a slumber party with the girls! They eventually caught up with each other at the KAABOO festival in 2018.

TLC were last invited as special guests on the show back in 2011, when the ladies took to the stage to perform a medley of their hits, “No Scrubs” and “Waterfalls“, and were joined by the Top 13 girls in the competition to help them perform on the latter song. They also opened the show with a first time performance of their 2003 hit, “Come Get Some“, featuring Lil’ Jon.

Other performers announced for the Season 21 finale include Season 2 stars Clay Aiken and Ruben Studdard, Ellie Goulding, James Blunt, Jazmine Sullivan, Jelly Roll, Kylie Minogue, Lainey Wilson, Lauren Daigle, Pitbull, and more.
