Katy Perry dating John Mayer?
The popstar has been linked to several showbiz names since her split from comedian Russell Brand, with Mayer the latest on the list.
Sources claim that the two stars were spotted out in Soho LA last week, before heading back to her house to share a pizza.
Guests at Soho House who saw the pair said "they were all over each other", reports The Sun.
Perry and Mayer have also been spending time together in the studio as they work on new material for Perry's next album.
Mayer said in a recent interview that he wanted to "completely avoid drugs, alcohol, clubbing, red-carpet events, dating celebrities and anything else that would detract from the music".
Since splitting from Brand, Perry has been linked to French Chanel model Baptiste Giabiconi and Florence and the Machine guitarist Rob Ackroyd.
