In the photo, taken before she joined the cast of Coronation Street, Sydney sports dark brown waves cascading to her midriff.

This is in stark contrast to her current on screen look.

Fans were quick to react to the blast from the past.

One surprised follower asked: “You’re a natural brunette?”

Another exclaimed: “You look so different Sydney!”

But it’s not just her hair that’s making waves.

Over the weekend, Sydney stunned fans with her incredible singing voice after posting a clip on Instagram.

Accompanied by a friend on guitar, she performed a soulful rendition of Another Love by Tom Odell, captioning the video: “Enjoy us messing about—just a bit of fun.”

The comments section was flooded with praise, including from her on screen mum, Vicky Myers, who plays DS Lisa Swain.

Betsy is grieving the loss of her boyfriend Mason Radcliffe, played by Luca Toolan, who was tragically killed in a knife attack.

The devastating scenes have been widely praised for their realism.
