The superstar has released her new single Perfect Illusion and has been out promoting it in London

Lady Gaga has been impressing fans with her raunchy outfits this week – but not her new single.

The superstar , who is in London to promote her latest track, Perfect Illusion, stepped out in another boob-baring top and a tiny pair of hotpants as she flaunted her newly-toned bod and performed at a former working men’s club in Hackney.

Mark Ronson, who is co-producing her new album , warmed up for the star, real name Stefani Germanotta, with a TWO hour DJ set until she finally appeared at 1.25am.

She only performed material for 25 minutes, including her new track, which social media users aren’t too excited about after it dropped this week.

One wrote on Twitter: “I just heard Gaga’s new song… It was absolutely terrible. I cringed for the 45 seconds I was listening.”

A second added: “I normally enjoy lady gaga. But my first impression of this new song is terrible. Anyone else? @ LadyGaga # MusicFriday.”

A third also posted: “Lady Gaga song is awful isn’t it? Sounds like an album track that should never have been released.”

The Guardian also branded her comeback ‘under-whelming’, writing: “There’s barely room to breathe, for the singer or the listener. When the song runs out of choruses less than two minutes in, it even resorts to the dreaded truck driver’s key change.”

But not everyone thought it was dreadful, with one writing on the social media site that her track is BETTER than rival Beyonce’s Formation. Hmmmm, we’re not sure we’d agree with that.

The 30-year-old singer, who has split from fiancé Taylor Kinney, has left fans waiting three years for new material and flew into London after writing the track on a vintage typewriter with Aussie act Tame Impala, according to The Sun newspaper.

Gaga appeared on stage after a champagne party in Berlin, Germany, and managed to stay awake until the wee hours before heading back to her hotel.
