Johnny Manziel -- I Went House Shopping with Von Miller

Johnny Manziel is now admitting he jumped the gun when he told TMZ Sports he was living with Von Miller -- but says the two DID look at houses together.

Manziel went to Instagram to clear up RoomieGate -- writing, "My bad V ... We were looking for some houses together didn't mean to get you caught up!"

Over the weekend, Manziel clearly told our photog the two were living together in L.A. Miller later denied the claim but expressed love and support for the QB.

The feeling is clearly mutual -- Manziel ended the post by wishing Miller good luck on "Dancing with the Stars."

As for the roommate situation -- no word if JM and VM actually found a place together or if they still have plans to shack up.
