Actress Reese Witherspoon and singer Ricky Martin will be the guests on Neil Patrick Harris' upcoming television variety series "Best Time Ever".
The 42-year-old actor, best known as Barney Stinson on the sitcom "How I Met Your Mother", said Witherspoon will be the first celebrity guest announcer on "Best Time Ever with Neil Patrick Harris", reported Entertainment Weekly.
Harris, who is a go-to awards show host, also said that Martin will participate in a game in which he will sing his hit "Livin' La Vida Loco".
The viewers at home will be asked on the spot to finish the line when Martin suddenly stops singing.
The show, an adaptation of the British program "Ant & Dec's Saturday Night Takeaway" will feature stunts, skits and pranks.
Harris said audience members, in the studio or at home, can win everything from cars to "toilet paper and dog food."
The eight episode series will debut on September 15 on NBC.
