As for Jessica, she is grateful for her friendship with Billy, “For him to give his time and his talents and share them with me. It was a great experience and I hope we can do more music together.”

Her new song Who We Are premiered Tuesday on Ryan’s radio show. “It makes me nervous, Oh my gosh,” she said, “I haven’t had a song on the radio in a long time.”  She was inspired to write the song after traveling the world for her new VH1 TV show called “The Price of Beauty.”
