Lady Gaga proved that she is truly comfortable in her own skin when she released a naked video of herself practicing a series of exercises to raise awareness for a Kickstarter campaign.

The 27-year-old singer, who took a break from music due to hip surgery, recently spent three says at a retreat in Upstate New York, learning the Abramovic Method. The technique is explained as "a series of exercises designed to heighten participants' awareness of their physical and mental experience in the present moment."

Gaga has previously flaunted her side boob and butt before, but this is the first time she is showcasing her entire body without clothes.

The two-minute video shows the Bad Romance singer sitting on a tall stool in a river, bending over in a forest, standing in a lake with two yellow spikes covering her eyes, and laying in bed covered with gigantic crystals.

The Kickstarter campaign has already raised more than $220,000 from over 1,000 backers, HollywoodLife noted.

Gaga has long been a fan of performance artist Marina Abramovic, the woman behind the campaign. The two collaborated on Gaga's upcoming album, ARTPOP.

"I'm obsessed with this woman," Gaga said of Marina in a 2010 interview. "She is so incredible."

Gaga, who is scheduled to to perform at the 2013 MTV Video Music Awards on August 25 previously said that her new album would feature her collaborating with a number of art-world luminaries.

Her first ARTPOP single, "Applause," will debut on August 19.
