Ke$ha has designed an exclusive limited edition T-shirt to mark National Coming Out Day, which takes place annually on October 11. 

The singer teamed up with The Human Rights Campaign to produce a special top that will honour the occasion and an official statement on the foundation's website explains that the working partnership was perfect as Ke$ha's message of 'We R Who We R' promotes equality:

"As part of the Musicians for Equality series, the “We R Who We R” unisex T-shirt – named in honor of Ke$ha’s smash hit by the same name – features a purple zebra, the inspiring words, "We R Who We R," along with HRC's equality logo and Ke$ha's signature on the front."

The pop sensation is no stranger to supporting worthwhile causes as back in September she was appointed as the first Global Ambassador for Animals by the Humane Society International.
