Talk about a DOWNGRADE!

InTouch Weekly reports that Victoria's Secret model Miranda Kerr and super hot actor Orlando Bloom are over.

And, to make something shittier even more craptastic, the Oz catwalker has rebounded into the arms of her former flame, Brandon "Firecrotch" Davis!

Grossness.

This past Saturday, Greasy Bear and Miranda were spotting locking lips at two New York City clubs.

An eye witless says they were "full on making out" at 1Oak.

Orlando's ex was also spotted kissing Greasy at Beatrice Inn later that night.

"They didn't seem to care who saw," the witness reveals.

Miranda's rep denies the breakup with Orlando, yet the model was overheard telling Brandon about the split.

Davis recently called it quits himself with another Australian model, Cheyenne Tozzi.

An insider says, "Miranda always seems to go to Brandon when she has a fight with Orlando. He's her rebound guy."

How does Greasy pull the chicks?

What doe$ he have that's so appealing to them?
