When you're in NYC, you never know who you're going to run into ... like Ethan Hawke and Katie Holmes.
Ethan was hanging out on his stoop with his adorable daughter Indiana on Thursday, when who should just happen to be walking by but none other than Suri Cruise's mom. Don't you just love when that happens?
The two actors -- who both live in the Chelsea neighborhood -- chatted each other up for a bit before Katie went on her merry way.
And people think New Yorkers aren't friendly.
