Cheryl reportedly changed her bio on the photo-sharing site to read: "When people hate on you, it’s because you’ve got something they want."
While the statement has since disappeared from her profile, eagle-eyed fans captured it and shared it before she’d had chance to remove it.
Her page now reads: "All love Good vibes only."
Liam, who is 10 years Cheryl's junior, seemingly confirm reports that they have been secretly dating since December, when he changed his Instagram profile picture to a snap of them together.
It shows them looking pretty cosy, with Cheryl resting on Liam’s bare chest and flicking the peace sign.
Cheryl is reportedly in the process of divorcing her second husband Jean-Bernard Fernandez-Versini, after their marriage came to an end last year.
They wed in secret in July 2014 in Mustique, following a three-month romance.
The Sun revealed news of Cheryl and Liam’s relationship over the weekend, with a source telling the paper: “It was unexpected but they’ve both made each other incredibly happy.
“Their relationship developed very quickly in December after the 'X Factor' final where One Direction gave their final performance before starting their hiatus.”
When contacted by HuffPost UK, Cheryl and Liam's representatives both declined to comment.
