Criss Angel has given an update on his son’s battle with cancer.

In his recent interview with E! News, the famed magician and illusionist (born Christopher Nicholas Sarantakos) said that his son Johnny Crisstopher is still having a difficult time going through his treatments. Criss did admit, however, that some days are better than others — and one of those better days was when he took Johnny to Disneyland Resort.

"You know, Johnny had a rough time going through chemo, his treatments, blood transfusions, spinal taps, and he has Mickey Mouse that he loves to watch," Criss shared with the news outlet. "So, when he went to meet Mickey Mouse in person he had a smile from ear to ear. So excited, we had such beautiful time together as a family."

Despite Johnny’s continued battle with cancer, Criss has high hopes for his son's future. “I think Johnny is a very special boy and I think he's going to be more successful than I ever was," he told E! News. “I just want him to be happy and I want him to live a long happy fruitful life.”

According to Us Weekly, Johnny — whom Criss shares with Shaunyl Benson — was diagnosed with acute lymphoblastic leukemia last October. Although Criss revealed to Us Weekly in June that Johnny was already in remission, the toddler is still undergoing intense treatments in Australia, where Benson lives.

Since Johnny’s diagnosis, Criss has become a champion for cancer research.  In fact, he is working on a big fundraiser, Criss Angel Heal Every Life Possible charity event, which aims to raise $1 million to help fund research for cures for pediatric cancer.

The event, which will be held on Sept. 12 at the Luxor Hotel & Casino, will feature performances or appearances by Angel himself, Cirque Du Soleil, Blue Man Group, Wayne Newton and Jerry Lewis, among many others. According to E! News, the fundraiser, has already received backing from fellow Las Vegas performers including Britney Spears, Jennifer Lopez and Céline Dion.

"It's amazing. You know, people love children, and people are good when it really comes down to it," he shared with E! News. "I personally called every single celebrity up myself. It took me some time to do, but I've called every single person. And I appealed to them on behalf of these children.”

“When you have a child that has this horrendous disease, you can relate to the families from a different perspective," Criss added. “So Shaunyl and I made the decision to use this in a positive way. You know, this is so much bigger than me.”
