Everyone took advantage of the fact that St Patrick's Day was on a Sunday this year and went all out!

A very happy belated birthday to our favorite Irish man and all-around gent, Hozier! The singer was in full St Patrick's Day spirit as he celebrated his birthday on the road in Charlotte. 

Plenty of other celebs got into the March 17 mischief yesterday. Be prepared for some amazing baby St Patrick's Day outfits, a pretty cool leprechaun trap from Neil Patrick Harris, and plenty of them forgetting that we've outlawed the phrase "St Patty's Day..."

In 2011, I visited the tiny town of Moneygall and got to walk around in the house where my great-great-great grandfather Falmouth Kearney lived his early life. I'll always be grateful for the warmth and generosity of the Irish people. Happy St. Patrick's Day! -Barack O’Bama pic.twitter.com/abDtarFbR5
