The Capital Weekender With Ministry of Sound 10pm - 6am
The 'Last Friday Night' singer has revealed that she turned down an offer to replace Kelly Rowland on last weekend's The X Factor.
Kelly was forced to pull out as her role as a judge due to illness and was replaced by former winner Alexandra Burke.
Katy said she was originally offered the chance to step in for the 'Down For Whatever' singer, but couldn't do it because she had a gig in Aberdeen, reports the Evening Express.
“I would have loved to but I just didn’t have time. I might have felt out of the loop as the show is not at the beginning," she said.
Meanwhile, Kelly is currently on her way back to the UK to continue mentoring the girls on this year's series.
