If we are to believe the rumors, Katy Perry and John Mayer are a couple again, but it’s just for fun.

Sources told E! News the pair is “back on” and enjoying their “casual” relationship.

Weeks after their breakup, Mayer told Ellen DeGeneres, “Coupling is a tricky thing.”

“They are just hanging out,” a source explained. “They are not putting a label on it.”

Having split in March, the lovebirds met again after 3 months when Perry invited her ex to the party she held for the Memorial Day.

Perhaps still in love, the couple quickly resumed their relationship.
