During her couch interview, she was a typical mom, gushing about her son Milan's many talents.

Everything is possible in the digital age and with an app. Jimmy Fallon and Billy Joel demonstrated that fact on 'The Tonight Show.'

Apparently, being 'Tonight Show' host means that you can get access to a lot of wild stuff, like private phone chats (with split-screen video, most improbably) between President Obama and Russian President Vladimir Putin about the situation in Crimea.
