Jesse James and his wife Bonnie Rotten might be calling a truce — because just a month after their messy court drama, they’re back in the same orbit.

Check out the clip … the estranged couple was all smiles at the Barrett-Jackson Palm Beach Auction over the weekend, cruising around in a vintage ride and even hitting the stage together during bidding.

Now, don’t go calling it a full-blown romantic reunion just yet — there was no PDA — but they also weren’t at each other’s throats … which is quite the shift, considering a judge recently ordered Bonnie to stop threatening Jesse or risk jail time.

As we reported, Jesse previously accused Bonnie of repeatedly punching him and even biting his thumb — claims that led to cops slapping cuffs on her after spotting injuries on him.
