Shailene Woodley thinks George Clooney and Kate Winslet are "groovy".
The 'Insurgent' star has worked with both stars on past films and has admitted she is "obsessed" with the 'Titanic' actress.
She said: "It is ridiculous but do you know what's even more ridiculous, they're actually really rad human beings. They're just groovy people. Why wouldn't you love them?
"Kate - she's one of the funniest people I've ever met too. Maybe it's just the British humour; she's so witty and so quick. She's incredibly intellectual and really intelligent and I think that just aids to her humour. I'm obsessed with Kate Winslet."
The 23-year-old star also praised the "generous (and) grounded" George, who she worked with on the 2011 film 'The Descendants'.
Speaking on the Radio 1 Breakfast Show with Nick Grimshaw, she said: "He's incredible. I worked with him five years ago and he really shaped the life that I lived just based on examples that I picked up from him. He's one of the most generous people I've ever met and also so grounded.
"He's one of those people who understands everything could be taken away from him in an instance and he'd be totally fine ... He sees the bigger sides of life; he's still very worldly and has a good vision of the world and doesn't have a tunnel perspective."
