One woman may be receiving most of Hugh Jackman's kisses these days -- that'd be his wife of 17 years, Deborra-Lee Furness -- but the Wolverine star spent his youth practicing with another famous lady: Olivia Newton-John.

Only, the Grease actress never knew about it.

"I remember when I was a kid growing up in Australia, all I wanted to do was be able to travel," the 47-year-old actor reminisced onstage druing the 2016 G'Day Los Angeles Gala on Thursday, People reports.

"I didn't have posters of footie [soccer] stars or rock stars up on my wall," he continued. "I had a map of the world literally next to my bed, and I used to lie in bed and dream of all of the places that I would go to when I was older."

The Aussie then caught himself and admitted that he did have one famous face displayed in his bedroom. "I did have a poster of Olivia Newton-John up on my wall, which I literally kissed," Jackman fessed up. "Maybe even practiced tongue-kissing on. I'm not sure!"

Just a few days prior, Furness' mother, Fay Duncan, received the Order of Australia on Jan. 25, and the couple recorded a sweet message congratulating her.
