"Wait u didn't think I would forget about National Selfie Day! DUH," Kim tweeted out, alongside a snap of her torso in what appeared to be a pretty revealing corset, failing to acknowledge Sia's message, which so far has more than 4,000 retweets.
But Sia's call-out certainly isn't the first time Kardashian has been blasted for her love of fur.
After numerous calls to ditch the fur by anti-fur supporters, Kardashian was flour bombed because of her controversial clothing choice back in 2012 as she walked a red carpet in New York.
PETA denied that they were directly behind the attack in a statement issued to TMZ but claimed they supported the individual who opted to throw flour over Kim, who was not wearing fur at the time.
"Whoever threw that flour may reach her when our polite appeals did not," the anti-fur organisation added.
Kim later defended her decision to wear real fur during an appearance on NBC's The Today Show, where she claimed that it was her "choice" to drape herself in the animal item.
"I believe everyone has the choice of what they want. It's not illegal to buy fur," Kim said on the morning show. "I think it's a personal choice but I don't think it's okay to assault anyone."
According to The Daily Star, an insider close to Kardashian revealed back in January that "Kim doesn't want to upset anti-fur fans, especially by the way she dresses North," after she was blasted for dressing daughter North West in what appeared to be a large fur coat.
The insider then admitted that Kardashian has supposedly vowed to replace her furs "with a new roadkill wardrobe."
