The sexy dress also featured a low back and a fairly low-cut neckline, and Fanning teamed it with peep-toe heels and a nude clutch bag.

As she posed on the red carpet with her hand on her hip, the U.S. star certainly looked older than her 18 years.

She wore her blonde hair down straight and proved that she can do glamour, compared to her laid-back look last weekend.

It revolves around Fanning's character, Tessa, who is dying of leukemia and compiles a list of things she'd like to do before passing away.

Top of the list is her desire to lose her virginity, and of course Irvine plays her love interest.

The dark-haired star was less glitzy with her attire and opted for a floor-length black dress, but she still looked fantastic.
