Liam Hemsworth had plenty of support from girlfriend Miley Cyrus at Monday's Los Angeles premiere of The Hunger Games.

Hemsworth, 22, was dapper in a Dolce & Gabbana black suit while Cyrus, 19, was draped in a high-waisted skirt from Emilio Pucci with a bustier.

The young lovebirds have been quite the red carpet pair since meeting on the set of their 2010 romantic drama, The Last Song. In 2010, Hemsworth and Cyrus made their debut as a couple when they arrived at the premiere of the film, based on the Nicholas Sparks novel of the same name.

Three years later, the two have done everything together, from award shows (they were super glamorous at last month's Oscars) to an upcoming episode of the newly revived Punk'd (Cyrus gets the last laugh).

At Monday's Hunger Games premiere, Cyrus could barely contain her excitement.

I'm probably going to see this about 13 times . . . I'm going to be a fan [of the movie] soon after this comes out. I'm going to be addicted, she told E! News.
