Lady Gaga looks 'Gaga-gantuan' on during Amsterdam concert

Maybe it’s a case of the stoner munchies. 'Born This Way' singer has said she is a marijuana fan and enjoyed Dutch pit stop in city where it's legal

Lady Gaga looked positively Gaga-gantuan at her concert Monday in Amsterdam.

The 26-year-old diva barely squeezed into an ill-fitting leather one piece during the show that revealed a little too much of her backside for the “Paparazzi” cameras.

Compounding the questionable outfit choice for a performer who’s considered a fashion pioneer - fishnet stockings that didn’t quite roll all the way up her exposed cheeks.

Maybe it’s a case of the stoner munchies.

Gaga went native during the Amsterdam show, taking a few puffs from what appeared to be a marijuana joint while performing on stage.

In a video captured by a concertgoer, the “Just Dance” singer is handed a wrapped cigarette from someone in the Dutch audience.

“Holland, is it real? Don't tease me,” says Gaga, pulling open the wrapper. “Oh, it's real.”

After lighting it up and taking a few long puffs, Gaga throws the lit joint to another fan in the crowd at the Ziggo Dome.

Amsterdam, where pot smoking has been legalized, seems the perfect fit for Gaga, an admitted fan of the "medical" drug.

The New York product, “Born This Way” as Stefani Germanotta, has admitted in the past that she dabbled in harder drugs, but cleaned up her act - almost completely.

"'I am a little bit part of the green club," she told the hosts of "The View" last year.

During her Amsterdam concert, Gaga used the opportunity to extoll the virtues of pot. She even joked that she would lobby President Obama to legalized marijuana worldwide, according to London's The Sun.

"I want you to know it has totally changed my life and I've really cut down on drinking," she told her Dutch Little Monsters. "It has been a totally spiritual experience for me with my music."
