The High Street Honey, 21, will be presented with a £3,000 Tiffany engagement ring by boyfriend Gary Greenhill as soon as they are reunited.
But she may have to wait a while as the ex-Berwick Rangers player is working on the other side of the world for a year.
Speaking about their romance for the first time, Gary, 23, told how he and Karly had just begun living together in Perth, Australia, when she was told she had been accepted on BB.
He said: "It was actually Karly's idea to come here to start a new life together.
"I'm keeping my fingers crossed that she won't fall in love with anyone in the house and she'll save her soccer strips just for me!"
Gary got a one-year contract with Perth Soccer Club earlier this year and Karly- who is wearing his Promise ring in the BB house-flew out to join him, hoping to get modelling work.
The Fife pair, who met through mutual pals four years ago, enjoyed six sex-fuelled weeks in Oz before she heard she was picked for the show and flew home.
Gary said: "When she arrived in April, I hadn't seen Karly for four weeks, so the first thing we did was make passionate love all night.
"Karly is a wee Scottish terrier between the sheets."
And Gary reckons his glamour girl-who keeps fit by pole dancing-will be pretty wild in the BB house too. He said: "If she sees Sophie topless, she won't be able to keep her hands off those enormous knockers.
"She's not prudish at all. She won't be shy about showing a bit of flesh in the BB house."
Gary insists Karly, who wears blonde extensions, will be a knockout on the show. He declared: "She's the sexiest thing on two legs."
