American television host and comedian Jimmy Fallon paid tribute to St Patrick's Day by teaming-up his little green friend, Kermit the Frog, to sing It's Not Easy Being Green.

In the video, 39-year-old Fallon dons a green "Kiss Me I'm Irish" t-shirt along with some patriotic badges and a striped leprechaun hat.

Before he joins in singing the sweet song with The Muppets star, Fallon can be see waving a mug full of green liquid, saying: "Kermit, don't you know today is the easiest day to green."

To which, Kermit replied: "Do you know what, that's a very good point."
