Katy Perry And John Mayer Back Together? Couple Reunites For A Sleepover, DJ Diplo Still A Part Of ‘Dark Horse’ Singer’s Life

Are Katy Perry and John Mayer back together? Such is the question of fans following the couple's recent reunion. The two reportedly dined together at a friend's abode in Beverly Hills, California. While the two arrived separately, the "Love Song for No One" hit maker reportedly spent the night at the 30-year-old singer's house.

According to the source of Daily Mail, the 37-year-old male singer stayed at Perry's house until the next afternoon. Prior to Katy Perry and John Mayer's split, the two have spent two years of on-and-off romance.

With Katy Perry and John Mayer's reunion, does it mean that DJ Diplo is already out of the equation? As per one insider of Hollywood Life, the romance is still on although the "Fireworks" songstress is keeping things privately.

"Diplo is still a part of her life, but she is keeping it very, very private. After Russell and John, she doesn't want to have the same media storm she had with them because that took a toll on those relationships and really was a main reason for the trouble," said the source to the publication.

Perry's main reason for being secretive is "because she wants it to work." She reportedly believes that the press contributed greatly to the falling apart of her marriage with comedian Russell Brand.

Since DJ Diplo is still with Perry, will he support the latter's alleged plan of dissing Taylor Swift during her Super Bowl halftime performance?

 "She wants to make a statement with her performance and show that she is the biggest female act in the world and she wants to show that to everyone including Taylor, who she has a feud with. In Katy's eyes, no one can compete on her level," said one source to the Hollywood Life.

News of their feud surfaced when Swift allegedly wrote "Bad Blood" because of how Perry sabotaged her show. DJ Diplo then created a campaign to get Swift a "booty."
