Happy Star Wars day! Famous fans of the franchise took to social media today to celebrate the film series's unofficial holiday of May the 4th (be with you), sharing Instagrams and Tweets featuring their favorite characters and quotes.

One of the best? The snap that Ansel Elgort posted featuring his head pasted onto Han Solo's body with the caption "May the 4th be with you" and the hashtag #Ansolo, which is the actor's DJ stage name. Cast members from the movies and relatives alike got in on the action—Star Wars: The Force Awakens stars John Boyega and Daisy Ridley both posted to mark the occasion, while Rachel Bilson (whose partner is Hayden Christensen, aka Anakin Skywalker in Episodes II and III) 'grammed a throwback of herself holding a poster of characters from the films.

One thing's certain: The Force is strong with these celebrities. Check out all the #MayThe4th posts shared today below.
