“Don’t Forget the Lyrics” is about to get a little more interesting — beginning this Thursday, February 21 at 9 PM ET/PT, music stars will be joining the karaoke singing competition. Tune in for Bret Michaels, Boyz II Men, Kevin Cronin and Kimberley Locke, as well as Gloria Gaynor and Kenny Loggins in upcoming weeks.

This Thursday’s episode will feature Boyz II Men, playing for the charities the Lili Claire Foundation and the TJ Martell Foundation. Not to worry, Boyz II Men will also be singing from their latest album at the end of the show, with a medley of “Same Old Song,” “Reach Out” and “End of the Road.” The songs are from “Motown: A Journey Through Hitsville USA.”

In upcoming episodes of “Don’t Forget the Lyrics,” Bret Michaels competes for Juvenile Diabetes Research Foundation and St. Jude Children’s Research Hospital, Kevin Cronin represents the MusiCares charity, and Kimberley Locke is playing for Camp Heartland.

While Gloria Gaynor and Kenny Loggins aren’t competing for charity, they will stop by “Don’t Forget the Lyrics” to sing “I Will Survive,” “I’m Alright” and “Footloose.”
