Back in black: Lady Gaga, 33, was seen leaving her hotel in New York City on Monday in an all-black leather ensemble ahead of a concert at Harlem’s iconic Apollo Theater

Gaga showed off her shoulder and upper arms with the semi-skimpy outfit, which featured a rolled-up black leather bandeau.

The minimal top highlighted her flat midriff, and she paired it with a high-waisted black leather skirt with a prominent and irregularly shaped belt buckle.

The Born This Way singer wore black gloves that reached above her elbows and toted along a black handbag.

She elevated her 5ft1in stature with a pair of black platform boots, and stuck to the dark monochromatic color scheme with a pair of large black sunglasses.

Her bleached blonde tresses were held up in a high, tight bun.

Though Gaga (real name: Stefani Germanotta) was on her way to a very real performance, fans were left disappointed about another future performance that seems to have petered out.

The Joanne singer was the subject of a rumor that she and her A Star Is Born co-star and director Bradley Cooper would perform a surprise set of songs from their Oscar-nominated film at England’s Glastonbury Festival, held June 26-30.

A collaboration had been suspected by some fans as Bradley originally played a secret set at the festival in 2017, which was filmed for the movie.

DJ Edith Bowman added fuel to the fire by hinting at a secret during a TV appearance.

‘Well, I may know one, but I can’t possibly say,’ she said coyly.

She’s noted for her seemingly limitless supply of striking outfits, and Lady Gaga didn’t disappoint ahead of a performance on Monday.

The singer/songwriter was seen leaving her hotel in New York City in an adventurous all-black leather ensemble that put her tummy on display, after already showing off a chic biker jacket earlier in the day.

The 33-year-old Oscar-nominated actress was on her way to perform a show at Harlem’s iconic Apollo Theater.

Abandon all hope: Festival organizer Emily Eavis confirmed the set wouldn’t be happening on Twitter

Any hopes of an on-stage reunion were soon quashed by festival organizer Emily Eavis, who tweeted: ‘Before this one gets out of control… the answer is no, that isn’t happening.’

She ended the tweet by reminding fans that a local cinema was showing the film on Friday.

Later, Bowman claimed her hinting had been fueled by the American Sniper star’s own statements to her.

‘I had Bradley Cooper [on] talking about A Star Is Born. And when I spoke to him, I was like, ‘I just wanna see you guys do a gig, play it live.’ And he was like, ‘Jackson’s dead!’’ she explained.

‘He said, ‘Well, we have been talking to Nick [Dewey, Glastonbury booker] and Emily about it — we’d do The Park Stage.’

The DJ also apologized for fueling the rumor on Twitter.

‘So sorry this has grown arms and legs. Blame Mr Cooper.’

Gaga performance Monday night at The Apollo will find her in front of a much smaller audience than she normally performs for.

She recently ended another run of her Las Vegas residency, which began in December 2018.

The pop superstar performs two different shows while in Vegas, a more traditional concert that focuses on her hits and fan favorites, as well as a stripped-down show that features a number of solo piano renditions and jazzy arrangements.
