The pair allegedly had a "secret fling" towards the end of X Factor which rekindled in 2015 when she split up with her bae.
Now, the 39-year-old has been spotted rocking a Harry Styles, or should we say a Hairy Styles tee while partying it up in London town.
The star also took to Instagram to share a boomerang and a vid of the shirt and cheekily captioned them: "Hairy Styles...💁🏽😜💇🏾" and "It's a vibe🐰".
