The 32-year-old "Fight for This Love" hitmaker said she loves all of her nieces and nephews, which is exhausting, reported Female First.
"I have 12 nieces and nephews of all ages and I love them all to bits but it's exhausting. Any aunt knows one of the best things is that after all your fun you can hand them back to their parents. It's knackering."
The singer said she and her husband Jean-Bernard Fernandez Versini, have no plans to have a baby "anytime soon" as she is enjoying being an aunt.
Cheryl is currently judging season 12 of British music competition "The X Factor", along with Simon Cowell, Nick Grimshaw and Rita Ora.
