She might have been known for those blonde locks of hers, but yesterday Ola decided to give her hair an overhaul.
Waving goodbye to her lighter tresses, Ola debuted her darker 'do and we're loving her new look.
Taking to Twitter, the 32-year-old shared her hair makeover with her followers.
Posting a selfie of herself and her new hair straight from the salon, she tweeted: "Boom!!! I did it!!! #Brunette."
On seeing her new look, many of the dancer's fans were quick to comment on her transformation.
One user told Ola she looked "absolutely stunning as a brunette", while another tweeted the star: "That's gorgeous, you look so different!"
And, they weren't the only ones who loved her new bonce...
Ola's husband of 11 years, James Jordan, shared his views on her colour change and by the sounds of things, we think the Celebrity Big Brother star is a fan.
He tweeted: "Last night I slept with a Blonde. And tonight I'm going to sleep with a Brunette #ThatsHowIRoll."
Meanwhile, Ola is currently enjoying some time to herself ahead of Christmas as she and her Strictly dance partner Steve Backshall were voted out of the competition over the weekend.
Finding themselves in the bottom two with Casualty actress Sunetra Sarker and her partner Brendan Cole, Ola and Steve's dance-off performance wasn't enough to save them being sent home by the judges.
Although judge Darcey Bussell opted to save the pair, the remaining judges all decided to save Sunetra - with head judge Len Goodman claiming she had the cleanest footwork on the night.
Strictly Come Dancing continues this Saturday 29 November at 7pm on BBC One.
