One Direction appeared on David Letterman this week, and member Niall Horan got a big surprise on the show!
Actor Dustin Hoffman was also there (you might have seen him in his recent movies A Series of Unfortunate Events or Kung Fu Panda, as well as classics like Rain Man and The Graduate). Before the interview started, he leant over and gave Niall a huge kiss.
Actually, if you look closely, Dustin has his hand over Niall's mouth so it's not a real kiss with lip-to-lip contact, but it's still pretty funny!
