"Best Time Ever with Neil Patrick Harris" is keeping the A-list power going for week 2 with a star-studded lineup, the network announced Tuesday (Sept. 22).

Among NPH's guests this week are Emmy-winner Alec Baldwin as the celebrity guest announcer; Seth Meyers making a special appearance; Joe Jonas and Britney Spears working with Harris on "Voices In Your Head," a prank segment as Spears interviews potential bodyguards in Las Vegas; and Bonnie Tyler of "Total Eclipse of the Heart" fame as this week's "Singalong Live" performer.

NPH also teases that he's learning a new skill for this week's "End of the Show Show," which last week featured Harris pogo-sticking into a freakin' backflip. How can he possibly top that? If anyone can, it's Neil Patrick Harris.

"Best Time Ever" airs Tuesdays at 10 p.m. ET/PT on NBC.
