Rumor has it that former celebrity couple Katy Perry and John Mayer have rekindled an old flame. The last time we saw Katy and John together was February, right before the couple broke up! Could these two singers have reignited their tumultuous romance?

On Monday, the ex-lovers were seen having dinner together at a friend's home in Beverly Hills. Although they didn't arrive together, they obviously enjoyed getting to update each other over the meal. Later that same evening, Mayer allegedly followed the 'Roar' singer back to her home, and didn't leave until the next day.

For those that don't know, Katy and John began dating in the summer of 2012, soon after she divorced her ex-husband, Russell Brand. The new couple broke up and made up several times before their last split in February. At the time, Perry was in the middle of a huge tour, and her work was the source of great argument between Perry and her 37-year-old partner.

After John, Katy began a new relationship with Diplow, a DJ, but that did not last very long because the pop star was reportedly "never serious."

In Harper's Bazaar, Katy Perry admitted that she had to turn to therapy to help cope with her traumatic break-ups. Although disheartened by the lack of love, Katy explained that the most important thing we can do is builds a "foundation of self-love" first.

Today, the singer has declared her desire for a partner who won't run from her success. "They say they're not, but it comes out in the long run," Perry explained.
