Legendary Chelsea club The Roxy will make a return Sunday as a Gay Pride pop-up.

The original closed in 2007, but will be channeled at the Best Buy Theater, says Gene DeNino, who bought The Roxy in 1985 where Madonna and Cher once performed.

Dress for Sunday’s bash, which will rage till 7 a.m., is billed as,“ ’90s Chelsea Boy, Drag Queen, Hell’s Kitchenettes and Sci Fi Kids.” OK!
