"Let there be blood." That was the unofficial motto last night at the Copacabana in Times Square, where Bob the Drag Queen and Kim Chi served up Halloween realness at the Bloodbath party, featuring semi-naked muscle boys, drag princesses, Power Rangers and more.

"Me and [business partner Mitch Ferrino] have always wanted to hire all of the New York queens and pay them a fierce wage and get together," Bob told NewNowNext. "You don't have to pick and choose where to party—you can party in one spot with all of us."

How economical!

Bob described her outfit, created by Season Four queen LaShauwn Beyond, as "a blood-spatter gown with just a touch of bloody-lady p*ssy."

Later in the night, she performed her new track, also titled "Bloodbath." The video, which dropped on Friday, is appropriately spooky but was a bit of a rush job.

"It was directed by me and my friend Cheyenne Picardo," Bob told us. "We did it five days ago. From scratch to finish, it took us three days."

There was plenty of drag talent on hand: Dusty Ray Bottoms performed a medley that ended with "Bottom of the River" by Delta Rae, while Pixie Aventura conjured up tunes from Wicked. Both were on fire—literally, at one point.

Other notable queens in attendance included Monet X Change, Sasha Valour and Aja, with Alex Newell running around in a black leather dominatrix look.

Then, of course, there was the queen of costume couture herself, Kim Chi, sporting head-to-toe rubber.

"I knew the theme was Bloodbath, says Bob's Season 8 co-star, "so I wanted to come dressed as the executioner of everyone who came to the party. Queen Of All The Killers!"

Pointing to the latex lumps protruding from her body, she declared, "These are intestines."

She was there judge the costume competition, with $3,000 to the grand-prize winner.

"I am looking for creativity and their attention to detail," Kim explained. "Attention to details like rhinestones or hemmed edges is what really separates a hot-glued mess from a couture piece."
