Ashton Kutcher and Mila Kunis’s Sydney

THE “sexiest woman alive” and TV’s highest paid actor snuck into Sydney yesterday to catch a break and check out the koalas.

Fresh from squashing some out-of-control pregnancy rumours, Mila Kunis and Ashton Kutcher kept a low profile as they visited Wild Life Sydney Zoo and hung out with some local celebs.

Sydney Confidential reported that the couple were “paying customers” and made a quick visit to see the koalas. “They never requested anything and just enjoyed a typical experience,” a spokeswoman for the zoo said.

“It was just the two of them and while they didn’t want any photos taken, they were very pleasant and friendly.”

Brian McFadden and DJ Ruby Rose were first to blow the whistle on the couple’s romantic getaway, boasting on Twitter that they had dinner with the stars at the Three Blue Ducks restaurant in Bronte. Also there was Mel B, her husband, McFadden’s wife Vogue Williams and web entrepreneur Brian Chesky.

Kunis, 28, is currently in between film projects and is preparing to shoot the sci-fi thriller Jupiter Ascending with Channing Tatum. Kutcher, 34, meanwhile, is on a break from filming sitcom Two and a Half Men.

US reports suggest the pair are all-but living together. “Like any new couple they are inseparable,” a source said. “They’re staying with each other most nights. Mila’s practically moved in to Ashton’s Hollywood home.”
