Fitness trainer Curtis Brown referred to Cheryl as her new husband's 'babby momma' in a recorded interview yesterday (July 17).
"Don't get mad at me, but your baby momma is hot," he says. "She's very gorgeous. She is a great singer. She's awesome."
Curtis is a friend of Cheryl's husband Jean-Bernard, so could he have been let in on a secret?
His comments came just hours after Cheryl's former Girls Aloud bandmate Nadine Coyle sent her a tweet asking her to 'Come join the baby club.'
Aww @CherylOfficial you must be having an amazing time. I am so happy for you! Good luck with everything. Come join the baby club. Best ever

Cheryl replied with three blow-kiss emoticons.
Cheryl only revealed on Sunday that she and JB had married in a secret ceremony in Mustique. So we don't expect they'll be confirming whether the rumours are true any time soon.
But one thing Cheryl has been very vocal about is her desire to start a family. Way back in 2012, she predicted that she'd be the first Girls Aloud mummy, despite being single at the time after her marriage to Ashley Cole ended.
"Who will have the first Girls Aloud baby?," she pondered. "I'm probably the most broody out of us all, but you kind of need a man for that to even be an option! I do have 10 nieces and nephews, so they keep me very busy."
Kimberley Walsh and Nadine may have pipped her to the post, but will Cheryl be next?
