From green shirts to green bikinis, the stars were embracing the festive hue as they celebrated St. Patrick’s Day on Monday!

And, thankfully, they were posting pics the entire time.

Mariah Carey was soaking up some St. Patty’s Day sun. The singer shared a sexy snapshot of herself celebrating poolside in a teeny weenie, green bikini and a (temporary) shamrock tattoo.

Jessica Simpson’s fiancé, Eric Johnson, sported a "Kiss Me, I’m Irish" tee, which obviously brought him some luck ... and a holiday smooch from his bride-to-be.

And the Kardashian clan was also feeling festive. Kendall Jenner rocked a mini green hat that read, "I’m a Wee-Bit Irish" as she posed for a celebratory selfie with big sis Khole Kardashian. And Khloe posted another shot with her adorable nephew Mason!
