"They seemed very comfortable together and kissed several times. It was a cold night and they held hands and John pulled her in close when she got cold," the source told E! News.

Last weekend, Perry, 30, and Mayer, 37, were seen having dinner at the Sunset Tower in Los Angeles. No one has caught a picture of the couple yet.

Last February, Katy Perry and John Mayer broke up for the third time.

An insider told Radar "Katy is giving John another chance because she feels like there could be something there... John pursued Katy relentlessly because it drove him crazy seeing her with Diplo."

According to reports, Katy and John started dating some time in August 2012. Perry and Russell Brand had just separated. Since Perry and Mayer broke up last time, Katy has been linked with DJ-producer Diplo.

In an interview with Harper's Bazaar, Katy Perry spoke about ending the romance with Mayer, saying: "I had to learn about taking care of myself before I could take care of others. I want to mommy everyone. I want to take care of them. I want to save them, and I forget myself in the meantime. I learned that through therapy."
