Locking lips with Liam Hemsworth? Kate Winslet has surely had worse days at the office.
The Oscar-winning actress, 40, engages in some very steamy scenes with the 25-year-old actor in their new film, The Dressmaker, set in the 1950s and filmed in the Australian Outback. Unsurprisingly, Winslet's 15-year-old daughter, Mia, had a strong reaction to her mom's latest on-screen love interest.
"When I told my daughter that I was shooting the scene that day she spluttered... I took it to be jealousy," Winslet confessed on BBC's The One Show on Wednesday.

"I did feel quite bad for Liam," the actress added. "He's a sweet guy, but I couldn't stop giggling."

In a separate interview with This Morning on Thursday, Winslet continued to praise her handsome co-star.
"Liam is a lovely, lovely guy, much is made of how he looks and he's physically extremely beautiful, but he's a fabulous chap and was really up for mucking in with the rest of us," she said. "But my daughter, Mia, was extremely jealous, along with all her friends."
Just last month, Winslet proudly celebrated her milestone 40th birthday. "I want to celebrate who I am, what I've learned, how hard I've worked, and how much more I've still got in me," she told Gotham Magazine in this month's cover story, as first revealed by ET.
And though she's 15 years Hemsworth's senior, Winslet marveled at how the pair looks together on-screen in an interview with The Daily Mail.
"When he arrived on set, I remember thinking, 'Does it show that we're different ages?' and on screen, it really doesn't," she said. Moments later, she joked: "Either I look good or he looks really f**king old!"
We're gonna go with the former on that one!
