The Playing For Keeps star, who is also a L’Oreal ambdassador, says she always considered being part of the show.
Lucky for Olympia, she had a trusted sourced to ask for advice when deciding on whether to do Dancing With the Stars or not - her half-sister and former pop star Holly Valance, 35.
“Well, Holly had been on Strictly Come Dancing in the UK, which is basically Dancing with the Stars – it’s the same concept. She got to the 11th show. I asked her how it was and she goes, ‘F---en’ hard!’
In hindsight, Valance agrees with her older sister.
“She said it was really hard, she said it was fun. And she’s right, it is really hard, but it’s also so much fun.”
And her boyfriend, fellow actor Luke Bracey, 29 – who she prefers to stay mum about – is one of her biggest fans.
“He’s very supportive. I’m very happy,” she shyly tells WHO.
