The 2013 Young Hollywood Awards took place last night, with our favorite young pop stars coming out, like the ubiquitous Selena Gomez, her shared namesake Becky G --the "G" is for Gomez-- and Austin Mahone.

It was a more casual event, but that didn't stop the red carpet walkers and attendees from hitting style high notes.

Here's how they looked!

Miss "I Just Turned 21 and Had a No. 1 Record" Gomez donned an LBD at the ceremony. We like her strappy heels.

Becky G's emerald green dress was amazeballs since it sparkled and because it popped against her gorgeous skin. It also played peek-a-boo with us.

Austin Mahone is certainly gunning for The Biebs' throne. How long until he gets a sleeve of tattoos?

Two up and comers, hanging and hugging.

And two AWESOME male voices -- Miguel and Mahone. Wouldn't a duet with these two be somethin' else?

Cody Simpson... he's so blond.

Cody and his sis Alli look like twins with their locks, don't they?
