The 'Love Made Me Do It' hitmaker is one of the comedian's celebrity guests on the BBC One comedy show this Saturday (05.01.19), and she was left embarrassed during the 'Send To All' challenge - which involves a made-up text being sent to an celebrity's contact list - when her dad, Garry Tweedy, replied to the message about being a naked art model for the star's "homework".

Reading out the text he wrote on the singer's phone, Michael, 42, said: "Hi babe! I'm getting private art lessons and my homework this week is life drawing.

"Would you come round and pose naked for me?

"It'll only take a few hours, we can have a good natter and don't worry I'll whack the heating up. If you'd rather we can position fruit and stuff in front of your naughty bits. Please say yes, need to know tonight!"

The brunette beauty replied: "Oh you actually wrote please say yes?"

Michael said: "You want a bit more matter of fact. Not so needy."

Cheryl added: "Yes."

Breaking into laughter, Michael joked: "Just for clarification, out of this whole text - you've just asked everyone in your phone to come round naked so you can draw them, but you don't want to sound too needy?"

In a comical turn of events, the former Girls Aloud singer's dad replied to the text confessing he'd only need a grape to cover his modesty because of how cold it is in Newcastle.

Reading out the message from Garry, Michael said: "It's cold up here. I'll only need a grape!"

Michael McIntyre's Big Show continues this Saturday at 7pm on BBC One.
