Jackman: J-Law has 'no ego' and is 'authentic'

Hugh Jackman loves that there are "not a lot of surprises" about Jennifer Lawrence.

The Australian actor really enjoyed working with the 23-year-old beauty on 'X-Men: Days of Future Past' and found her down-to-earth attitude refreshing.

Asked what he likes best about, her said: "There are not a lot of surprises.

"What you see is what you get, and I've met her and worked with her...The way you imagine her to be is how she is.

"She's not only one of the most talented actors I've met, she's one of the most authentic. Very down to earth, no ego. She has a lot of fun doing what she does."

And the 45-year-old star had a great day off camera when the actress and her boyfriend and their co-star Nicholas Hoult joined him and his children Oscar, 13, and Ava, eight, on a day out to a theme park.

Hugh - who is married to Deborra-Lee Furness - told E! News: "We were just on roller coasters -- no security, no this, no backup. Just getting around.

"And she just manages to handle this incredible fame and power that she has with real ease. On top of that, she's a brilliant actor.

"I would happily hang out with those guys because they're really terrific. I had a great time with them."

Meanwhile, Michael Fassbender said Magneto is "more Machiavellian" in the latest film.

The 37-year-old actors stars as a young Erik Lehnsherr, a.k.a. Magneto, in the superhero film, and insists his alter-ego has stronger beliefs now.

Talking to reporters at the film's premiere in London's Leicester Square on Monday, he said: "In this film he is Magneto. He is much more singular in his beliefs and methods. He's much more Machiavellian."

Magneto was at odds with Professor X for decades however with a mutant annihilation on the cards it forces him to form new alliances and Fassbender enjoyed seeing this develop.

He added: "I just love the character. There is so much history in the character before I have arrived in his shoes. There's so much to play with, he's very complex. I love the relationship he has with Professor X."

The Hollywood hunk was joined by co-stars Ian McKellen and James McAvoy on the blue carpet.
