Katy Perry and John Mayer have reportedly broken up earlier this year and while the Birthday singer may be living up her single life, the Daughters star is allegedly having trouble moving on.

"He really misses her and would do anything to get her back," the source added.

Despite Mayer having issues with moving on, there have been several reports that Perry is actually doing really well now that she doesn't have a boyfriend.

"She finally decided 'f--- it.' I'm going to do what I want to do and I don't care what people think," a friend of the singer's told People.

"She is happy being single," the source added. "I don't see her getting into another relationship for a very long time. Why would she? She has a fantastic career, a ton of friends and is generally happy with things. She thinks that a relationship will complicate things right now."

The "Dark Horse" star is apparently going to be focusing on her work right now and not let a boyfriend get in the way of that.

"She's looking for something showstopping [for her tour]," the source said. "Something that will grab the attention of everyone. She can't focus on that if she's dating someone. Right now, she needs to have a one-track mind, and it can't be about a boyfriend."
