On Monday night, the 48-year-old illusionist ditched his rocker, jewelry-heavy style for a dark, clean-cut suit and sunglasses for the inaugural Criss Angel HELP (Heal Every Life Possible) charity event at Luxor Las Vegas.

Proceeds from the benefit went to Johnny Crisstopher Children's Charitable Foundation, an organization Angel created after his son was diagnosed with acute lymphoblastic leukemia. The charity is working to "raise awareness of pediatric cancer and provide funds for research, treatment, and, ultimately, a cure."
