I don't know what it is about VINCE VAUGHN
, but no matter what he's talking about -- it's hilarious! You'll see for yourself when he's on the show today! Vince is in the hilarious new movie "Couples Retreat," and speaking of couples, he's gonna tell me about his engagement! We'll also play his favorite game: Humdinger -- we know he's good at guessing, but can he hum too? And you know SCARLETT JOHANSSON
is a great actress, but did you know she is also an amazing singer? She's teamed with PETE YORN
for her second album called "Break Up," and the two will perform their song "Relator." It will be their first time performing on TV -- and it's on my show! I've also found another batch of Hidden Audience Talents and I think they might be the greatest so far (and you thought the guy who could kick himself in the forehead 25 times was the best!).
