As if Los Angeles hadn't flipped enough over "La La Land," today, April 25, is "La La Land Day." Celebrations of the award-winning musical will be taking place all day and you can even visit "Seb's," a recreation of Ryan Gosling's dream jazz spot in the movie.

And it's not just LA: Jazz spots in five cities — Chicago (Andy's Jazz Club), Los Angeles (Blind Donkey), Washington, D.C. (Mr. Henry's), New Orleans (d.b.a.) and San Francisco (Le Colonial) — will transform into Seb's, according to THR.

The celebrations in LA began at 8 a.m. this morning with Mayor Eric Garcetti declaring today "La La Land Day." Then Bandaloop aerial dancers dressed like Gosling and Emma Stone in their famous dance number twirled down the face of LA City Hall.

And if you can't make it to LA for the costume displays and dance classes, you can livestream the whole thing on Facebook.

Onhand for the festivities were the Oscar-winning director Damien Chazelle, composer Justin Hurwitz, production designers David and Sandy Wasco and choreographer Mandy Moore.

Hurwitz told THR that today's celebration is "very cool, adding, "With the film and the music, we were hoping to capture certain flavors, colors and feelings of Los Angeles, so to have the actual city embrace the film is very flattering. It's really cool that this movie has become a touchstone for so many people in so many places."

This fun continues this Sunday, April 30, the Hermosa Beach Pier will be transformed back into the scene where Ryan Gosling first sang the Oscar-winning song "City of Stars." Musicians will perform songs from the soundtrack and the vintage lamp posts (which were originally placed there just for the film) will be reinstalled and lit.

Coming up on May 26, Hurwitz will take over the Hollywood Bowl for "La La Land in Concert," which will feature the live score against the backdrop of the film.

That's a lot of "La La Land" love!
