Kennedy, who can now be seen on TV's "Ghost Whisperer," will also perform in viral Yoostar videos and participate in promotional activities for the brand that include helping to discover talent nationwide.
"Yoostar continues to add to its library of content across genres to provide our audience with a uniquely immersive and personalized entertainment experience. Jamie Kennedy's blend of improvisational comedy and acting talent make him the ideal brand ambassador and creative force for the introduction of our comedy channel," Patrick Bousquet-Chavanne, chief executive officer of the Yoostar Entertainment Group, said in a statement.
The Yoostar Comedy Channel is expected to be up and running on the Internet next month.
"I think what the team behind Yoostar has accomplished is simply awesome. If only I had this when I was trying to break into the business! It makes everyone a star and I am so excited to be a part of it," added Kennedy.
The Yoostar entertainment system gives people the opportunity to interact with green-screen technology to insert themselves directly into famous movie and television scenes, where they can perform with, or replace, the original actors, then upload their performances to www.yoostar.com and share them on their favorite social networking sites.
Yoostar will retail for $169.95 at Best Buy starting Tuesday and is already available at Bloomingdale's and Yoostar.com, with additional scenes available for $.99-$3.99 per clip on Yoostar.com.
