This past weekend marked the passing of Belgium's SPNCon, in which stars and crew members of the hit show talk on panels and have meet 'n' greets.

While there, it seems that one of the show's stars, Jared Padalecki, has a newly blossoming relationship with one of the makeup artists that work on the show, Willow Parker (younger sister of heartthrob Jackson Parker from 'Shadowhunters').

Parker and Padalecki got cozy on a bus from the convention venue to their sightseeing destination, and then never took their hands off of each other while traveling around and taking in everything around them with Padalecki's costar, Jensen Ackles.

All of this when Padalecki JUST (not even a year ago) had a very public and seemingly nasty breakup with ex-wife Elaine Thomas, who he also met on the show.

Although we can't confirm, sources tell us that Thomas has quite a bit to say about the new couple, with one of the quotes we received being: "It's not going to work. No way he's going to put in the effort to make it work. Not with her. She's just a rebound."

Again, we can't confirm or deny the above quote, but if it is true, it definitely sounds like there's going to be trouble in paradise sometime soon!
