"[You're] right," Kesha said. "I need to find sympathy and empathy for her. She's so mean. It's hard."
"Do you want me to see if I can talk to her?" Gaga said. "I know she's mean."
After the messages were made public this week, Gaga decided to address the situation.
"[Katy and] I have grown up in the industry together," she tweeted.
"We've gone through both celebrations & differences [with] each other. These are old texts.
"We've matured, gotten over the past, love each other & share deep respect," she continued. "Katy is my friend and is truly a kind soul. End of story."
Showing there are no hard feelings, Perry replied:
"Love you too friend. Onward and upward."
Perry denied Kesha's claim that she was sexually assaulted by Dr Luke, real name Lukasz Sebastian Gottwald, in a July 2017 deposition.
When asked, she replied "Absolutely not."
