Jennifer Lawrence thinks Chris Pratt is the "hardest-working person" she's ever met.
The Oscar-winning actress appears alongside the 37-year-old star in the new romantic sci-fi movie 'Passengers', and Jennifer is full of praise for her on-screen co-star.
She shared: "Chris Pratt is the hardest-working person I've ever met in my life."
Jennifer, 26, also appears on screen with the likes of Michael Sheen, Laurence Fishburne and Andy Garcia in the much-anticipated new movie, and she has revealed how much she relished the production process.
She told ET Canada: "It was a beautiful experience, because we all were so passionate about it."
The new movie centres on the story of two spaceship passengers who are on a 120-year journey to another planet when they are woken 90 years too early.
Jennifer explained: "It becomes very clear that there's something really wrong with the ship, and gravity starts to go out, and the robots are all failing.
"Jim and I are in a race against the clock to figure out what is wrong with the ship, and how we can fix it - not just to save our lives, but the lives of the 5,000 people who are on the ship."
Meanwhile, Jennifer recently revealed that she "works very hard" to keep her life private.
The Hollywood actress said she likes to keep out of the spotlight as much as possible, despite being one of the most recognisable women in the world.
She explained: "You might think you know me, but when you approach me you're a total stranger to me and I'm scared. [I get] very protective of my space. It took me a long time to be able to do that.
"If I'm eating dinner and somebody comes up and a flash goes off from someone's iPhone camera, I am really rude to that person. Then other people at the restaurant will see and be like, 'Oh, damn, I don't want to do that.' Privacy is a full-time job and I work very hard at it."
