Lady Gaga has never been one to hide away her body, but after piling on 30 lbs it seems she is reassessing her wardrobe.

Lady Gaga, 26, covered up her new curves in a long sleeved white coat as she left her hotel in Amsterdam on Wednesday night.

The star teamed it with sky-high heels and dark sunglasses with her head wrapped in a white scarf.

She signed autographs and handed out perfume samples to her fans, who had waited for hours to meet her.

The outfit was positively demure for Lady Gaga. But perhaps she had seen photos of herself the previous night.

Then the 5 ft 1 star had strutted on stage in Amsterdam in a series of typically skimpy costumes.

But rather than revealing her toned body, this time they showed bulging hips and thighs, cascading tummy and double chin.

Nutritionist Majid Ali, who has not treated the singer, told RadarOnline: “Gaga appears to have gained at least 30 pounds.”

Lady Gaga is on the European leg of her Born This Way tour, but the obvious weight gain seems to be dragging her down.

This is a far cry from what Lady Gaga looked like just a few months ago, when her muscular legs and toned, six-pack abdomen held spectators in awe.

Lady Gaga has been open about how hard she usually works to maintain her trim physique, and caused controversy earlier this year by revealing her diet habits.

Writing on her Twitter page, she said: “Just killed back to back spin classes. Eating a salad dreaming of a cheeseburger #PopSingersDontEat #IWasBornThisWay.”

Lady Gaga also admits she loves food, especially Italian cuisine, and can’t get enough of it.

“The rumors I am a dab hand in the kitchen are completely true,” she said.

“I come from an Italian family – what more can I say? I love to cook. I am really good at Italian food. So I make great meatballs, pasta and all sorts. I love it.”

Despite her weight gain Lady Gaga was polite to her fans, who had waited for hours to meet her.

Lady Gaga handed out samples of her new perfume, Fame, and signed autographs.
