Now this is “Crazy.”

CeeLo Green fell off of a horse at a birthday party celebrating late rapper Shawty Lo in Atlanta Wednesday night.

Footage from the bash shows the “F–k You” singer, 47, stumbling off the mare shortly after he made his grand entrance into The Bank venue.

Green – who was rocking a jacket with a large chain and his signature sunglasses – rode into the party atop the stallion with two men in cowboy hats leading the way.

At one point, it was evident that the horse was feeling nervous – and about to lose balance.

“Man, CeeLo got a horse in this bitch,” one partygoer, who was filming the scene, yelled just before catching the incident on camera.

Green, however, didn’t let the tumble kill his vibe as he quickly jumped up to his feet with a smile on his face.

Even the emcee made light of the situation, joking that the “spirit” of Shawty Lo “did that s–t” – as the late rapper “is a comedian” and “funny like that.”

Guests came together Wednesday night to pay tribute to Lo, who died in a car crash in Sept. 2016 at the age of 40. The date would have marked his 47th birthday.
