The SHUT UP! singer has been confirmed as the support act for Williams' upcoming tour - who she has loved ever since he found fame in the nineties pop group.
Kelly says, "I was so excited when I was asked to do the Robbie Williams tour because I have been a fan since Take That days.
"I can't wait until the summer comes."
Robbie said when announcing the tour, "I love Kelly. Her don't-give-a-s*** attitude reminds me of me. She rocks."
Robbie has become pals with her wildman rocker dad while he has been living in Los Angeles and was present when Ozzy was given his own star on the Hollywood Walk Of Fame last year (02).
