The stars are getting in the St. Patrick's Day spirit! Our favorite celebrities are taking to social media to document their celebrations of the holiday, from donning their brightest green ensembles to partaking in a bubbly beverage.

Some of our favorites? Michelle Monaghan's very festive snap (above), which she captioned: "Happy #stpatricksday!! #OOTD #irishgirl." We also loved Niall Horan's 'gram of himself drinking a pint of Guinness, where he gave a shout out to his home country: "Happy St. Patrick's day everyone . . Always proud of our little nation."

Check out all the best St. Paddy's celebrity Tweets and Instagram posts below.
