Sharon Osbourne paid tribute to the "endless" career of Kinky Boots composer Cyndi Lauper as she was awarded a star on the Hollywood Walk of Fame.
The singer was honoured at the famous landmark following her Grammy and Tony award-winning score to the hit Broadway musical, which is also being performed in the West End.
Sharon described Cyndi, who had a string of hits in the 1980s including Girls Just Want To Have Fun and True Colours, as a "true original".
"She's had an endless career which spans decades," Sharon said.
"She's a prolific songwriter. She's an incredible performer. Nobody sounds like Cyndi Lauper. She's instantly recognisable.
"She's a true original. She's been original from the day she was born with her style."
Sharon, who is reportedly in line for a return as a judge on the X Factor, left Cyndi close to tears as she praised her True Colors Fund which supports gay, lesbian, bisexual and transgender teenagers.
Speaking on stage, Cyndi said she had doubts about how the musical Kinky Boots would work out.
"One time I closed my eyes and actually asked my guardian angel, "Am I going to do OK?," she said.
"He just showed me an image of me as Dorothy with the lion, the scarecrow and the tin-man and I thought, 'OK I can do this.'"
Cyndi received her star along with Kinky Boots writer Harvey Fierstein, who referred on stage to Donald Trump's star which has been targeted by vandals following his controversial US presidential bid.
He said: "To think that Donald Trump has one of these. Listen, there's a very thin line between fame and infamy.
"I know which side I belong on. We're going to get a map for Donald."
