Lady Gaga Bares Butt on Date Night with Taylor Kinney!

Lady Gaga shows off her body in a completely sheer outfit displaying her lingerie while on a date night with boyfriend Taylor Kinney at the Chateau Marmont on Sunday evening (August 11) in Los Angeles.

The 27-year-old singer bared her butt in the outfit, that showed off her skimpy thong underwear.

After a short snippet of her song “Applause” leaked over the weekend, Gaga took to Twitter to assure her fans not to pay attention to criticism.

“Dont focus on ANY blogger criticism. I have been a producer/songwriter/musician for over 10 years. Trust the artist bloggers are not critics. The fans + music scholars are the best critics because they know the artist intimately. #STOPHarassingTheArtist we are here to entertain you,” Gaga tweeted. “Let’s make 2013 a year where music/talent/artistry is more important than gossip/fanwars I respect all fanbases 4 their passion #BeTheChange.”

FYI: Gaga is wearing a Saint Laurent crystal bodysuit.
