Hugh Jackman and Ryan Reynolds have been trolling each other for so long, its hard to put a finger on when it all began.

In a new interview with The Daily Beast , Jackman revealed his long-running faux feud with his friend actually started with another star: Scarlett Johansson.

How did it start? ... God, this is a classic sign where your feud has gone too long, where you dont even know why or how it started! Jackman admitted.

He recalled that it kicked off with some lighthearted teasing on the set of Wolverine, not long after Reynolds had married Johansson. (The pair were married from 2008 to 2011, before Reynolds married his current wife Blake Lively the following year.)

I met him back on Wolverine, and I used to ream him because I was very close friends with Scarlett, and Scarlett had just married Ryan, Jackman said. So when he came on set, I was like, Hey, you better be on your best behavior here, pal, because Im watching, and we started ribbing each other that way ... Then it all escalated with the Deadpool thing and him calling me out.

Reynolds superhero comedy Deadpool and its sequel hilariously targeted Jackmans Wolverine character over and over.
