Each year the clubbing of baby seals occurs on the ice floes of eastern Canada, with the annual activity due to happen next week. The campaign is to target the government's attempts to sell off baby seal fur internationally, reports Rolling Stone.
"I was lucky enough to get to watch a bunch of wild seals recently and truly fell in love with these amazing creatures," explained Ke$ha.
"Canada gets to be host to harp seals each year during their migration to the ice to give birth, which is beautiful and peaceful. But because the babies' fur is so soft, there are people who club and brutally kill these young animals.
"The Canadian seal slaughter is barbaric and archaic. My music and my fans are part of a movement of youth taking over the world with positive change. I know they'll help me and PETA ban the Canadian seal slaughter so the only place you see baby seal fur is in a museum."
Both stars have urged their fans to write letters of protest to Canada's Prime Minister Stephen Harper.
Ke$ha recently announced a handful of UK dates as part of her 'Get $leazy' tour, as well as confirming an appearance at this year's Glastonbury Festival.
