Katy Perry, John Mayer want their relationship to last
The on-off couple first started dating in 2012 and recently rekindled their romance after splitting last February, reported OK! magazine.
"It's different this time around. Both of them have changed, and after nearly a year apart they've realised what they want," a source said.
Mayer, 37, who released a duet, 'Who You Love,' with the 30-year-old beauty last year, is also said to be thinking about asking her to marry him in the near future.
