Robin Thicke was so “f–king drunk” while leaving a bar with his fiancée that he almost fell into a bush.

Eager photographers outside The Fleur Room in West Hollywood, Calif., Thursday night captured the inebriated “Blurred Lines” hitmaker and a mortified April Love Geary standing on the sidewalk while waiting for their ride.

After Thicke, 46, broke free from Geary’s stabilizing embrace, he attempted to re-enter the lounge — and nearly face-planted into a plant.

“Alright, bye, Robin!” Geary, 28, shouted like a fed-up mother as the bouncer lifted the stanchion rope outside the front door.

“God, that’s embarrassing. That’s so embarrassing!” the model exclaimed as she rushed over to hold up her soon-to-be husband.

“Don’t let him go in there,” she said to the security guard before looking at Thicke and adding, “Your bitch ass is so drunk.”

The pair then stumbled away from both the entrance and the paps, with the singer repeatedly saying, “My bad, my bad, my bad.”

But the brunette beauty wasn’t having it. “It’s f–king embarrassing. You’re too f–king drunk,” she said. “It’s just embarrassing.”

They continued their inaudible bickering, which included a lot of hand motions and head bobbing from the upset influencer.

After fiddling with her phone in an apparent attempt to track down their ride, Geary eventually held it up to her ear to see if she could better communicate with the driver.

While she was on the call, Thicke began to pester her and even attempted to wrestle the phone out of her hand.

Geary squirmed out of his reach and tried to walk away from him, but he kept following her.

“Take pictures of him grabbing me like that,” she encouraged the photogs before instructing her wasted companion to “stop” numerous times.

“F–king stop, Robin. Stop!” she said as the duo continued to squabble. “Leave me alone! Stop. Stop. Robin, they’re taking pictures. You better stop! You better f–king stop. You better stop. Stop. Stop. Stop!”

Geary, whose naked body is tattooed on Thicke’s arm, continued her pleas to no avail as she and the middle child of late actor Alan Thicke made their way to a black SUV that had pulled up near the curb.

With his arms wrapped around her shoulders, the chaotic twosome managed to fall into the car’s backseat.

It’s likely the scolding continued all the way home, where the couple’s three children — daughters Mia, 5, and Lola, 4, as well as son Luca, 2 — were likely asleep.

Robin is also dad to son Julian, 13, whom he co-parents with his ex-wife, Paula Patton.

The musician proposed to Geary in December 2018 after more than four years of dating. She has since vowed to not sign a prenuptial agreement because Robin is “not marrying anyone else after” the self-proclaimed “baddest bitch on the planet.”

Their reps did not immediately respond to Page Six’s request for comment.
