On Saturday, Oct. 22, 'Glee' star Darren Criss, YouTube sensation Rebecca Black, piano prodigy Greyson Chance, and Disney actress/singer Debby Ryan all attended Variety's 5th Annual Power of Youth Event. The Variety event, which was held at the Hub at Paramount Studios in Hollywood, celebrates "top young talent and their dedication to philanthropic and humanitarian causes closest to their hearts, while encouraging the industry and their fans around the world to get involved and give back."

Darren Criss was actually one of the honorees at the event, receiving props for his work with The Trevor Project, which is a campaign that advocates awareness and acceptance for LGBTQ youth. Other honorees included actresses Chloe Moretz (The Film Foundation), Hayden Panettiere (The Whaleman Foundation) and Hailee Steinfeld (Share Our Strength).

Criss looked studly as usual while at the Power of Youth event, wearing jeans, a button-up checkered shirt, and a camel-colored vest. Rebecca Black also kept it casual in a silk top, jeans and knee-high boots, as did Greyson Chance. However, Debby Ryan -- who Sean Kingston has admitted to having a crush on -- brought some glam to the party, wearing a charcoal blazer, red flare pants, and heels.
