Phillip Schofield‘s ITV co-star took to her Instagram page to share an unearthed snap of herself.
And the 38-year-old looked completely different in it to what she does now as she rocked brunette locks.
Holly was seen smouldering into the camera in the photo as she rocked a grey rollneck jumper and red trousers, which she pulled at.
Meanwhile she was rocking sultry makeup, including smokey eyeshadow and a soft red lip.
Captioning the post, Holly wrote: “Once upon a time in a land before blonde…”
Fans were loving the post, with it racking up more than 38,000 likes.
One exclaimed: “Ohhh my! You look gorgeous.”
While another told her: “Really suits you!”
A third added : “Blonde, brunette… still beautiful girl.”
Fellow This Morning star Rochelle Humes also chimed in, exclaiming: “I bloody love it.”
Holly is currently embroiled in some drama with claims of a ‘feud’ between her and co-star Phillip Schofield, 57.
However, the pair have both denied that there is any rift between them.
Holly even said this week she would quit This Morning if Phillip left.
In a clip from TV show Shopping With Keith Lemon, she was quizzed on what would happen if Phil quit.
She said: “If he left This Morning… well we’ve always said from the beginning that if either of us left then we wouldn’t want to do it as I can’t imagine This Morning without Phil, it’s us together!”
As well as This Morning, the pair also host fellow ITV show Dancing on Ice together.
