The 26-year-old singer once said that she would never wear fur because she hated it, reported Ace Showbiz.
PETA senior VP, Dan Mathews, pointed out three outfits GaGa wore - a Michael Kors fur she donned in London last year, a hot-pink Giorgio Armani fur coat she had last week and a wolf carcass she rocked in the poster of her movie "Machete Kills".
He questioned the 'Poker Face' hitmaker, "What happened? Are your stylists telling you that it's fake, or are you a turncoat?
"But by wearing those dumb furs in a heat wave, you're making yourself a target just like the mindless Kim Kardashian. As we plan our fall campaigns, please tell us whether what you gracefully told Ellen was heartfelt or just a pose."
In response to the question, Gaga tweeted, "For those press and such who are writing about whether or not my fur is actually real. Please don't forget to credit the designer HERMES. Thank You! LOVE, gaga."
She stepped out in Bulgaria wearing a Hermes fur coat while holding a puppy in her arm.
