We can't help but say just how great Kesha (formerly "Ke$ha") looks now! The singer behind favorites such as 'Tik Tok' and 'We R Who We R' walked the red carpet last night at a Humane Society benefit in Beverly Hills. This marks the pop star's first public appearance since checking into a rehab facility in January for an eating disorder.

Wearing a lovely, dark, sparkling and nearly see-through dress, the 27-year-old singer was all smiles and looked healthy and happy. Her unique style and once no shame attitude has led to some interesting red carpet fashion styles in the past, but last night she took the conservative and classy route, with the exception of coloring her hair slightly pink with a streak of green on her left side.

Kesha has been known to support animal rights in the past, having worked with the Humane Society as her passion of cause. In October 2012, Kesha was named as the Humane Society's "First Global Ambassador for Animals." The singer explained, "In my travels, I've seen many dogs living on the streets," she says. "On one trip, I found two dogs who had been literally superglued together. I finally managed to separate them, but this was on an island with no vet, no shelter, no resources to help these dogs. HSI's street dog programs can really make a difference in the lives of these animals.”

We're so happy that Kesha is doing well and supporting such a great cause. Keep up the good work!
