How Ryan Reynolds pranked Hugh Jackman for opening night of 'The Music Man'

The greatest prank war in Hollywood continues.

Hugh Jackman revealed the latest gag pal Ryan Reynolds pulled on him -- perfectly timed for opening night of his "The Music Man" Broadway revival -- in a recent social media post.

"I have the most amazing friends. Gorgeous flowers, champagne and heartfelt well wishes. I am blessed. And then … there's him," Jackman, 53, wrote on Instagram, tagging Reynolds, 45.

Instead of showing off the celebratory flowers and Champagne he received from loved ones, the Wolverine actor showed off a pair of framed photos of Reynolds that populated his dressing room at the Winter Garden Theatre.

One photo showed the "Free Guy" actor clicking his heels together in a mid-air jump, and the other was a sepia-toned sketch of him.

There was also a note on the framed photos awaiting those who zoomed in: "Hugh, good luck with your little show. I'll be watching."

Reynolds replied to the Instagram post in the comments, writing, "Haunting."
