The X Factor judge's phone rang during a music break and was answered by DJ Greg James, who took a message from Garry that he wanted Chezza to know he'd called.
Greg then encouraged Cheryl to ring Garry back on air - which she did!
Warning her dad he was on live radio and he couldn't swear, Cheryl asked what he'd wanted. "I was just calling to see how you are," said Garry. "How the night went and that and how you are doing."
"The night was good, dad," replied Cheryl.
When asked what he was doing, Garry said just chilling out in the garden, sitting in the sun.
"I love you, I'll ring you after," said Cheryl, before hanging up.
Aww. We wouldn't have minded listening to Chezza spill the beans to her dad on yesterday's perfume launch, especially has her new husband JB was there as well!
Cheryl launched her fragrance StormFlower to media in London last night, where she looked stunning in a floor-length lacy nude frock. The perfume is available from August.
