John Mayer 'Lying In Wait' To Steal Katy Perry Back From Orlando Bloom

RadarOnline.com has exclusively learned that John Mayer is waiting for Orlando Bloom to inevitably screw up so he can sweep in and steal Katy Perry back!

"John says he and Katy will reunite this year," an insider revealed. "He's laying in wait for Katy to come back running into his arms."

However, as RadarOnline.com reported, Mayer, 38, may have to bide his time for quite awhile since Perry and 39-year-old Bloom seem happier than ever together.

Not to worry, said the insider: "He's incredibly patient and has been planning this for a while."

According to the source, Bloom is nothing but a rebound for 31-year-old Perry, and Mayer has no expectation that his nemesis in love can go the distance with this new relationship.

"John's just very dismissive of Orlando and how this guy pretends to have substance when he's really nothing more than an international playboy, and a predictable one that," sniped the insider.

"John's virtual disappearance from the public eye has everything to do with the mind games he's playing with Katy, who he's still madly in love with," continued the source. "But he's trying to keep her guessing about his personal life and he fully expects her to come running back to him when things sour with Orlando."

After all, added the insider, "there's a load of unfinished business between John and Katy."
