The couple took a brief break from their on-again, off-again romance last year, but were seemingly doing better than ever recently. They recorded a romantic video for their duet, “Who You Love,” which premiered in December, and were doing joint interviews to promote it at the time.
In fact, the duo was even rumored to be engaged just last week, after Katy was photographed wearing a diamond ring on her left hand. Neither have confirmed the breakup yet, but John was noticeably absent during his lady’s recent trips to London and Milan. Plus, she’s heading out on a World Tour later this year.
