Even though Jennifer Lawrence is an Oscar Award winning actress, her "Hunger Games" co-star Liam Hemsworth insists that the young superstar has not changed a bit.

While on "Good Morning America" on Monday, Miley Cyrus' fiancé told the anchor that although she won the Academy Award for best actress nothing had gone to her head and turned Lawrence into a diva.

The 23-year old actor said, "You wouldn't even know, Jennifer had won an Oscar. She's great. Nothing has gone to her head over the last few years."

Hemsworth reflected on his first encounter with Lawrence, "When I first met her she was full of life and brings such a great energy to set."

He went on to say, "When you're shooting the tough stuff like the themes in the Hunger Games, it can be a little dark and she's got that great energy about her and she's still that way."

Fans can catch Jennifer Lawrence and Liam Hemsworth in the latest installment of the "Hunger Games" franchise, "The Hunger Games: Catching Fire" set for a November 22nd release.

However, Hemsworth spilled some juicy details about the third installment of the franchise "The Hunger Games: Mockingjay - Part 1" due in 2014.

The film finally gives his character, Gale Hawthorne some much needed screen time, he said, ''My character in the next one coming up, you get to see a little bit more of the fight in Gale and how much he cares about the whole thing. How he's willing to stand up for what he believes in.''

According to Virgin Media, he previously revealed that he read all three of Suzanne Collin's books before he auditioned for the film, he said, ''I read all the books before I met with anyone about the movie, and I became a fan of the books.

''As an actor, I'm always looking for scripts that I relate to, in some way, and things that are interesting and different. If it's combining romance and action, I'm not missing out on anything. I get to do it all.

''I want to do as many different emotions as I can. It's a pleasure to be able to do both, in the same film.''
