Lady Gaga spotted rocking out to her new favorite band

It’s only Wednesday, but Lady Gaga is already having a typically fabulous week.

On Monday night she was uptown, wowing high society with her Versace glistening-mosaic look and 10-inch heels at the Met Ball. But on Tuesday night, the New Yorker was roaming her old downtown stomping grounds at a show by British garage rockers Fat White Family.

Gaga and a small entourage descended on Greenwich Village venue Le Poisson Rouge to watch the London band, which is on tour promoting its second album, “Songs for Our Mothers,” which came out earlier this year.

The 30-year-old star looked carefree and did away with her denim jacket, wearing just a black bra, jeans and boots while she danced in the elevated VIP section for much of the show. She also attentively filmed some of the songs on her iPhone.

“I f - - king love this band,” she told The Post while backstage in the venue’s dressing room. “I wanted to keep my cool look together, but once I heard that bass line, I had to take [my jacket] off and just rock. I’m not the kind of person who becomes a superfan easily, but with these guys I was feeling it.”

Fat White Family formed in 2011 and released their provocatively titled first album, “Champagne Holocaust,” in 2013, winning critical acclaim for their combination of Velvet Underground-esque rock and roll and overtly seedy lyrics. Their feral live shows, during which the band’s singer, Lias Saoudi, frequently gets naked, have also become the stuff of legend.

But recently, the band has raised doubts over its long-term future. “There’s serious sociopathic, drug-addled [issues in the band]; almost everybody has some kind of personality disorder,” Saoudi told Vice in April. “You’re talking about some prize f - - k-ups and mentalists.”

Gaga also took a minute to chat and take snaps with Saoudi and guitarist Saul Adamczewski. “When people watch you guys play, they rage hard, and it’s like they leave their bodies,” she told the guitarist approvingly.

With her long-awaited follow-up to 2013’s “ARTPOP” due later this year, there’s no doubt Gaga’s picking up inspiration from one of the best and hippest groups around.

She’s not the only famous fan the band can boast. “The Walking Dead” star Norman Reedus is an admirer, as he told The Post last year, while Sean Lennon also has been an advocate of the group since its first American shows, even letting the band members stay at his home in the Catskills.
