Jerry to Sit with Jay

What's old is new again in Hollywood: NBC has announced that comedian Jerry Seinfeld will be the first and only guest on the premiere of The Jay Leno Show, joining previously announced musical guests Jay-Z, Rihanna, and Kanye West. Leno's new weeknight prime-time series begins September 14. Seinfeld, meanwhile, will be reuniting with Seinfeld co-creator Larry David (and the rest of the old cast) in the new season of HBO's Curb Your Enthusiasm. He'll also be returning to NBC early next year with The Marriage Ref, a reality series he's planning to produce.
