March 17th is a day when people all over the world celebrate Irish heritage. Celebs are no different, as they put on the green, white and orange and enjoy every little bit of heritage from the emerald isle.

They even enjoy some things that have nothing to do with Ireland - yes, we are looking at you green beer! 

Here's how some of your favourite celebrities celebrated the day. 

Liam Hemsworth 

"Happy St. Patrick’s day Ireland! Thanks for letting all of us celebrate it with u!! My grandma was Irish and I couldn’t be prouder. Light it up!"

Aussie hunk, Hemsworth, has Irish roots... well, he must have gotten his charm from somewhere.

Ellen DeGeneres

"Top o' morning to you! I hope everyone has a lucky day. #StPatricksDay"

It's a little known fact that nobody from Ireland has ever actually said "top o' morning" to anyone during a conversation. Nonetheless, that hasn't stopped Americans using the phrase as the quintessential Irish greeting. 

Mark Hamill

"Today would be a good day to deploy these #StPatricksDay images, because today.....  THE WHOLE GALAXY IS IRISH."

The man who played Luke Skywalker has actually been in Ireland many, many times. Most recently during a filming trip in County Kerry. Irish people love him and he appears to feel the same.

Melissa Joan Hart

"May the road rise up to meet you. May the wind be always at your back. May the sun shine warm upon your face; the rains fall soft upon your fields and until we meet again, may God hold you in the palm of His hand. -Irish Blessing for this lovely #StPatricksDay"

Sabrina the Teenage Witch star, Joan Hart, knows her Irish proverbs and she isn't shy in sharing them with her legions of social media followers. A great status for the day that it was. 

Kevin Smith 

"Happy St. Patrick’s Day from Kevin Patrick Smith - a guy who was very recently the beneficiary of some of that legendary luck of the Irish! May you never leave this world! But if you have to, may you be in Heaven an hour before the Devil knows you’re dead! #StPatricksDay"

Dogma director, Kevin Smith, recently had Irish luck on his side when he survived a heart attack. We are glad to see him on the mend and sharing such sweet comments over St Patrick's weekend. 

Josh Groban 

"Happy St Paddy’s day!! I will now dust off my pennywhistle and delight the neighbors through the walls with my highest notes!"

We don't know about you guys, but we certainly wouldn't mind hearing Groban sniging through the walls.

That's how your favourite celbs spent their Paddy's Day. We hope you lived a day just as charmed!
