HUGH JACKMAN and Ryan Reynolds are going to try to get along for 24 hours — but neither seems too confident they can pull it off.

The duo are (jokingly) enemies who have clashed since working together on 2009’s “X-Men Origins: Wolverine.” That film marked Reynolds’ first appearance as Wade Wilson/Deadpool, but it’s a version he’d like to forget.

On Monday, the Marvel stars called a day off from busting each other’s chops as part of the All in Challenge.

The All in Challenge — started by Fanatics founder Michael Rubin — has stars auction experiences to raise funds to feed the elderly, children and frontline workers amid the novel coronavirus pandemic. Once a star accepts, he or she then challenges another star to join the cause.

Trying not to get frustrated with each other, the two said in a video they will work a lemonade stand together for the child of the randomly chosen bidder.

Jackman nominated NFL star Drew Brees, Mariska Hargitay and Peter Hermann.

Reynolds nominated well-known retired astronaut Chris Hadfield and soccer star Ashley Lawrence.
