Nick Jonas has been appointed ambassador to Tv and radio presenter Ryan Seacrest's kids charity.

The former Jonas Brothers star will front the Ryan Seacrest Foundation, which is dedicated to inspiring today's youth through entertainment and education-focused initiatives.

Seacrest says, "Nick has been an amazing supporter of our foundation and recently brought smiles to our friends at Children's Medical Center Dallas, where he shared his own story of resilience and how he copes with being a diabetic. Nick

is an extremely talented artist, and it has been great to watch his rise to fame.

"But even more important, he is kind and has a generous spirit, which we know will inspire the thousands of children."

Jonas adds, "I'm thrilled to partner with such a remarkable charitable organisation such as the Ryan Seacrest Foundation. It's encouraging to see children continue to follow their dreams despite their struggles, which is something that is close to my heart."
