Upon her return from space, Kesha wasted no time in poking fun at Katy Perry. She posted a cheerful selfie with a Wendy's milkshake shortly after the fast-food chain playfully teased Perry's Blue Origin touchdown. The social media post by Wendy's X Twitter targeted Perry, who had just participated in an all-female mission on Jeff Bezos' New Shepard rocket. In response to a photo of Perry kissing the ground, Wendy's tweeted a reference to Perry's 2008 hit song, "I kissed the ground and I liked it."

Subsequently, Wendy's account joked about sending Perry back to space in response to news of her return. Kesha, known for her legal dispute with producer Dr. Luke, further fueled the situation by sharing a photo of herself enjoying a Wendy's shake without any caption or explanation.

The post attracted attention, sparking a debate among fans of both artists. Some criticized Kesha for dwelling on past events while others defended her right to shade Perry due to her ongoing association with her alleged abuser. The tension between Kesha and Perry traces back to a 2016 text where Kesha mentioned Perry had also been mistreated by the same individual she was suing.

Legal proceedings ensued, with Perry refuting the claims and a court ruling against Kesha for defamation. Perry distanced herself from the legal battle but remained connected to the case, causing ongoing public scrutiny. Kesha's lawsuit against Dr. Luke alleging a decade of abuse ultimately ended in a confidential settlement in June 2023.
