Holly Valance who? Kiss Kiss singer’s sister Olympia oozes sex appeal in …

And the star is obviously very proud of her work as she’s frequently seen posting pictures of herself in the underwear onto her Instagram account. 

Last month Olympia posted a picture of a stand in Paris with three giant snaps of her in her underwear on the side. 

She captioned it: “What’s better than 1 jumbo Olympia?… 3 I guess.”

Her fans agreed with replies like, “This should be the wallpaper in my room,” and, “Olympia you are my fav in neighbours Paige.”

Could Olympia be a bigger star than her Kiss Kiss sister Holly? Only time will tell.
