Miley Cyrus supported boyfriend Liam Hemsworth last night (12.03.12) at the world premiere of his new film 'Hunger Games'.

The singer-and-actress wore a figure revealing black cropped top and see-through long skirt as she posed on the charcoal and gold carpet with her handsome beau and admitted shooting the action film took its toll on Liam.

She said: ''I think the hardest part for Liam was being away from me. And his brother and his family.

''At least he's not in a tour bus and is in a nice hotel somewhere. It's a little less bumpy, a little more sleep.''

Liam - who plays Gale Hawthorne in the eagerly-anticipated film - also confessed it was hard being away from home but loved every minute of it.

Looking dashing in a black suit, Liam said: ''On one hand, it's hard being on your own, but on the other, I'm making movies and it's something I love. One of the great things about this job is traveling getting to see the country and the world.''

Miley says she will be accompanying Liam around the world to attend the film's other premieres with him.

She joked: ''I'm probably going to see this about 13 times. I'm going to be a fan soon after this comes out. I'm going to be addicted.''

Other stars at the premiere at the Nokia Theatre in Los Angeles included Jennifer Lawrence, who plays the lead character Katniss Everdeen, Josh Hutcherson and Elizabeth Banks.
