Kesha Gleefully Sips from Wendy's Cup After Brand Throws Shade at Katy Perry

Kesha is throwing fuel into her feud with Katy Perry.

The 38-year-old singer was previously involved in a years-long legal battle with music producer Dr. Luke and fans were shocked to learn that Katy decided to work with him on her new album Lifetimes, despite knowing what Kesha went through.

“I understand that [working with him] started a lot of conversations, and he was one of many collaborators that I collaborated with. But the reality is, it comes from me,” Katy said about her music last year.
