Criss Angel is known for his magic tricks and over the top illusions but right now his focus is on being a father to his 2-year-old old son, Johnny Crisstopher Sarantakos. Johnny was recently diagnosed with acute lymphoblastic leukemia.

Angel took to social media to thank his fans who have been expressing an outpouring of support for his family during this time. "4th day chemo -- Shaunyl, Johnny & I can't thank u enough for the overwhelming outpouring of love, prayers & support #amazing," Angel wrote via Twitter on Monday.

He also posted a picture of himself holding Johnny on Instagram with the same caption.

Johnny is currently going through chemotherapy treatments in Australia and Angel flew out to be with him. In light of this emergency, Angel had to cancel shows in Las Vegas following his son's diagnoses, People reported. Angel normally performs his show, CRISS ANGEL BeLIEve at the Luxor Hotel and Casino.
