“TMZ After Dark” has been tearing up the nightlife for a minute now … so naturally, the next step was bigger, bolder, raunchier — it’s our first-ever gay party on wheels!

We’ve honestly never seen a party like it — history went down Saturday night as celeb hosts Queer Ultimatum’s Vanessa Papa and comedian Izzy Rocha turned all the way up, raging with Ashlee Belzo‘s queer-owned production crew Girls, Gays and Theys.

The bar crawl kicked off at Jumbo’s Clown Room, bounced to Rainbow Bar & Grill, rolled through Beaches Tropicana … and wrapped at Roosterfish West Hollywood for the company’s massive third anniversary blowout.

If that wasn’t enough — surprise! West Hollywood Mayor Chelsea Lee Byers popped up, and we took her to Jumbo’s for the first time. Cameras weren’t allowed inside, so yeah … let your imagination do the heavy lifting …

The party spilled outside — we kidnapped one of Jumbo’s dancers, Caroline Blaike, cuffed her, and brought her aboard, where she delivered a lap dance to the mayor so steamy it literally fogged up her glasses🙈 … with the best DJs in town, Toxic Kitty and Liz Wentling, spinning.

So yeah, if you’re looking for the wildest party in town, hit up TMZ After Dark 🎶’cause you’re on the right track, baby… if you were born this gay! 🎶
