Nicholas Hoult has opened up on his Jennifer Lawrence, saying that fame hasn't changed her.

The actor maintains that their relationship has "pretty much [stayed] the same". The couple started dating in 2011 after meeting on the set of X-Men: First Class, but broke-up in January 2013.

The pair then rekindled their romance after reprising their roles in the upcoming X-Men: Days of Future Past.

The former Skins star said that Lawrence hasn't let fame go to her head. 

He explained to V Man magazine: "It's like that thing whereby you don't believe your own hype. Enjoy the good times, but don't get swept away with it.

"I think that's something she's capable of doing, and that's what makes her special, but yeah, it is very odd, and I am just kind of a bystander in many ways. It is well-deserved for her. I haven't really seen any change in her."

Hoult added that the only difference in their relationship is the amount of privacy they get, saying: "The privacy thing obviously changes but the rest pretty much stays the same."

The actor also explained that he loved working with Lawrence on the latest X-Men movie: "It's fun because in this business you are away from one another for long periods of time, so when you're on set together it's a brilliant thing, because you actually get to spend time together. Especially with this film, I got to spend time with her."
