Jennifer Lawrence used to ask Liam Hemsworth if he liked having sex with kangaroos.
The 25-year-old actress is known for her quirky sense of humour and she used to try to make her 'Hunger Games' co-star Liam, 26, laugh by saying outrageous things just before a take.
Speaking on the 'Graham Norton Show', Liam said: "She often, right before a take, would turn to me and ask me if I liked having sex with kangaroos - anything along those lines. You never really know what's going to come out of her mouth."
And when asked what his answer was, Liam joked: "Absolutely! That's what Australians do!"
Although Liam has now rekindled his romance with fiancée Miley Cyrus, Jennifer previously admitted that the pair had shared a cheeky kiss off-screen.
Speaking to Andy Cohen on 'Watch What Happens Live', she said: "Liam and I grew up together. Liam's real hot. What would you have done?"
Referring to her character Katniss' on-screen love triangle with Liam's character Gale and Josh Hutcherson's Peeta, Andy quipped: "I would say yes. I mean, I pick Gale over Peeta any day."
And Jennifer gleefully replied: "I did, at one point!"
She later joked: "I gotta call Liam!"
Meanwhile, Liam recently spoke about the emotional turmoil caused by his high-profile split from Miley in 2013.
He shared: "Of course it was hard, man. But at the time we were going in different directions and it's just what needed to happen. We were both super young and it was a good decision at the time--we both needed that.
"I make my decisions about what's going to make me happy, what I think is right and what I want to do, and I don't worry too much outside of that."
And although he refused to explicitly confirm that they are a couple once again, Liam gave a strong hint that they had rekindled their romance, which dates all the way back until 2009.
Asked about his relationship status, the Hollywood star said: "People will figure it out. They already have. ...They're not dumb."
