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.

Angel was joined by his 2-year-old son, Johnny Crisstopher Sarantakos, and the mother of his child, Shaunyl Benson. Several celebrities were also in attendance, including Mike Tyson, Cory Feldman, Gary Oldman, Jerry Lewis, Debbie Gibson, Vince Neil, Richie Sambora and Tony Orlando.

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."

In June, Angel happily revealed that his son was in remission. "I believe he will be healed," he told Us Weekly.

Johnny was still undergoing chemotherapy, blood transfusions and spinal taps, and receiving medical care in Australia where he lives with his mom. "What doctors found is you have to continue treatment to kill all the cells, as there is no guarantee," Angel explained.

Here's a look at his son's brave battle with cancer:
