At the second day of the MDA Show of Strength filming, singer and actor Jesse McCartney showed his support for the Muscle Dystrophy Association, and also gave ET an update on his current happenings.
"I'm the process of finishing, actually, some new music that I'll be releasing probably later this year," McCartney revealed of his fourth studio album. The 25-year-old star also mentioned a film project that had just wrapped.
"We're here for such an amazing foundation. Muscular dystrophy is something that a lot of people--my contemporar[ies]--don't know much about," the Departure singer said. "I think maybe that's part of the reason I'm here: to speak to our youth and build that awareness among people that are my age."
Also supporting the MDA was ET's Nancy O'Dell, who personally experienced the cruelty of muscular dystrophy when her mother struggled with motor neuron disease ALS (a.k.a. Lou Gehrig's disease).
"Had it not been for MDA, we wouldn't have known how to help my mom," O'Dell said. "I hope, along with MDA, that together...that we can find a cure for all these neuromuscular disease because it's definitely needed so that families don't have to go through the pain and suffering that I know too well."
