Ke$ha has urged her fans to "show animals love."
The 26-year-old vegetarian was horrified after watching a barbaric documentary about tigers.
The star, full name Kesha Rose Sebert, was so moved, she took to Twitter to urge her followers to respect living creatures and each other.
"Watching a mini doc about tigers being farmed and killed to make tiger wine," she wrote on the social network. "Makes me sick.
"We need to show each other and animals love. We all just need love. Please," she added.
The Tik Tok singer has previously spoken about her love of animals and has maintained she does not wear real fur.
Ke$ha spoke to The Phoenix New Times newspaper about why she is a vegetarian back in 2010.
"I just love animals, and I'm an advocate for animals rights, and my family has rescued dogs from all over the world," she declared.
"I don't believe in animal testing. If you see me in fur, it's always fake. Sometimes you see me wearing skulls, but those are all from roadkill."
Meanwhile a new documentary featuring the singer is only a month away from hitting MTV screens in the U.S.
Ke$ha: My Crazy Beautiful Life will feature the star drinking her own pee in the series, which was filmed by her journalist brother Lagan Sebert.
"It's my brother and his weird friend following me around for the past two-and-a-half years," she revealed to BBC Radio 1. "We didn't know what we were doing per se, but it's my little brother and he's my best friend.
"He's got me wasted at 6am. He got all the things you would want to see and all the things you wouldn't really want to see - making out with dudes, drinking my own pee, jumping out of a building, jumping out of airplanes, swimming with sharks...
"I was told drinking my own pee was good, I was trying to be healthy," she added.
