Katy Perry and John Mayer have reportedly bought a house together.

The couple rekindled their on/off relationship in June after Katy revealed she was ''madly in love'' with John and things have gotten so serious that they have splashed out on a love nest together.

A source told Hollyscoop: ''Katy and John picked out her new home together. They picked it out for them to start a life together. They live there together.''

Friends have also revealed that Katy, 28, and John, 35, have been discussing marriage although Katy - who tied the knot with former husband Russell Brand in a lavish ceremony in India - wants an intimate ceremony rather than a large bash.

The insider added: ''He has not proposed, but they have talked about getting married. My guess is they will be married but not with a big ceremony at all- she does not want that. Katy feels John is her soulmate and that he is the reason for her becoming who she is. I have never seen Katy so happy and I have known her for many years!

''Neither one of them really want kids at this point in their lives. With his new album and new projects she is currently working on, they both want to focus on their careers, but living together pretty much speaks for itself.''
