Katy Perry and John Mayer back together again?

Katy Perry and John Mayer have reportedly got back together again after calling off their sweet romance romance.

Katy and Johm have been getting close lately "talking over their feelings" to see if they can make their relationship work.

An insider told The Sun newspaper: "They're spending a lot of time at his house talking over their feelings and trying to see if they can make it work."

The couple who have had a notorious on/off romance since 2008 were reported to have called it quits last month for the fourth time, but the reason was unknown.

However, in the past they've stopped seeing each other because of their tight schedules and Katy's "trust issues" when she is "so far away" from him.
