On the morning of Valentine's Day the singer posted a snap of herself on Instagram striking a pose and grabbing her long locks, which are platinum blonde at the ends thanks to a chic dip dye.
She captioned the snap, "Do blondes have more fun???!!! I'll let you know #lorealFeria #blowout901girl!!"
Fresh-faced Cheryl, who often flits between being a brunette and blonde, looks delighted with her new hairstyle, with an open-mouth smile and dressed in a black leather and beige-coloured jumper.
As rumours continue that Cheryl, 30, will be returning to The X Factor, her new look could be ahead of her rejoining the judging panel along with music mogul Simon Cowell.
She teased fans with the biggest hint yet that she will be sitting on a judge’s chair by posting a Throwback Thursday picture on Instagram.
The snapshot, which has fuelled speculation that Simon has convinced her to come back on board the ITV talent show, sees her sitting next to Simon Cowell on The X Factor, pointing at him accusingly as the dad-to-be smiles coyly.
Simon, who famously axed Cheryl from the US version of the show in 2011, is said to have wooed her back with a butler service dinner over the weekend.
"It was just him and Cheryl," an insider told The Sun. "Simon was offering an olive branch. It was a very civil evening. "She was happy and loved talking about the show. It's pretty much nailed on that she'll be back."
