Liam tongue-tied on 'Twilight' comparisons

Liam Hemsworth is basking in the limelight with all the recent "Hunger Games" premieres, but when asked last week if he thinks he's on his way to being the next Robert Pattinson, he was at a loss for words.

"Oh, I don't know. He's uh . . . I don't know. I have no idea!" Liam, 22, laughed uncomfortably during his red carpet Los Angeles premiere.

The Aussie was a tad bit more talkative (just a tad) when "Access Hollywood" recently asked him how he feels about his flick being compared to "Twilight."

"It is scary," he admits and then proceeds to make an exploding sound.
