Katy Perry and John Mayer have reportedly got back together again.

The 'Roar' hitmaker and 'Gravity' rocker have been getting close lately ''talking over their feelings'' to see if they can make their relationship work.

After reports surfaced about their break-up, they are now believed to have been ''spending a lot of time'' at John's home together.

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.

A source previously told RadarOnline.com: ''The reason they have split in the past is because Katy gets busy. John can't handle the lack of attention, and she can't handle the trust issues she has when she's so far away. So they've learned that it's better to just take a break when they can't be in the same place.''
