The 25-year-old actress claims the Australian star and his older brothers, Chris Hemsworth and Luke Hemsworth, have some "disgusting" habits and are "the craziest family I've ever been around in my life."

Asked why she regularly calls her 'Hunger Games' co-star a "bear," the blonde beauty said: "He's an animal! His whole family, they're real animals. It's the craziest family I've been around in my life. The way that they communicate is so physical and crazy.

"It's like, 'Eat this scab and I'll give you five bucks!' They're disgusting. They're real bears; they're animals!"

The 'American Hustle' star also revealed Liam, 25, and Chris, 32, are always playing pranks on their friends.

She told Conan O'Brien on his self-titled US chat show: "Chris, one time, thought it was funny to bust in on his friend that was in the shower and cut his hair off. They're really intense."

Jennifer is disappointed Liam recently decided to become vegan.

The Oscar winner joked: "It drives me crazy because every time we're out to dinner, I'm like, 'You'd love this!' and he's like, 'I can't eat it!' "
