Lady Gaga has apparently been attending spinning classes in perfect make-up and hoop earrings.

The eccentric star was criticised for her weight gain last month, after sporting a slightly curvier figure onstage in Amsterdam.

Now the Poker Face star is allegedly getting back into shape with spinning classes at SoulCycle in Manhattan.

“She didn’t look big weight-wise at all,” a regular at the class, Kristin Breen, told the New York Daily News.

“She had on big gold hoops and red, perfect lips [and] a bandana folded and tied across her forehead.”

Gaga joined the 10.45am class on Saturday and apparently arrived “five to six minutes late”, accompanied by two friends.

Kristin said the singer didn’t look like she had broken a sweat after the hour-long session and immediately asked an employee if she could stay on for the next class.

A source at the second class says the 26-year-old “went nuts” when her hit Born This Way came on during the workout.

“She was hooting and whipping her towel around as she danced on her bike,” the eyewitness revealed.

“The instructor came over and danced in front of her bike.”

Gaga had revealed previously that she intended to lose weight, stating: “[I’m] dieting right now, because I gained, like, 25 pounds.”
