The who’s who of young Hollywood beauties stepped out in their glad rags for the 2012 Art of Elysium Heaven Gala last night.

Julianne Hough, Minka Kelly and Rachel Bilson were among the swarm of celebrities lending their support to the charitable event.

Minka looked resplendent in yellow and had the happy glow having reunited with boyfriend Derek Jeter recently.

Bilson’s choice of outfit was a little fairytale and had a tutu skirt while Hough went for a one shoulder body-hugging gown with daring thigh-high split.

Also in attendance at the event held at Union Station in Los Angeles were Kelly Osbourne, Amber Heard, Sophia Bush and Kirsten Dunst.

The Art of Elysium encourages actors, artists and musicians to give their time to enrich the lives of critically ill children.
