Miley Cyrus took the Big Apple by storm Wednesday … putting on a wild performance and then dazzling her gazillion fans in her super sexy outfit right on the street.

It all started with Miley’s concert last night … the singer jumped onstage and belted out a bunch of tunes off her new album, “Something Beautiful,” at Rough Trade Below in the famed Rockefeller Center in Midtown Manhattan.

Video shows Miley — clad in jean shorts, fishnets, a shirt and jacket — standing in front of a mic and singing one of her hits, “Easy Lover.”

Check out the photos … Miley — now wearing a sheer black dress with underwear and no bra — signs a slew of her “Something Beautiful” albums for fans gathered outside the hotel.

Miley even autographed a copy of the record for a fan who posted a pic on X earlier in the day. She wrote a message on the cover that read, “The Best Liam.” Of course, Miley took an obvious shot at her ex-husband, actor Liam Hemsworth, who she divorced in 2020.
