Hugh Jackman is hitting the tennis court, and he's calling out none other than Novak Djokovic to play with him. The famed Golden Globe winner and X-Men actor would have the courage to challenge a 12-time Grand Slam champion.

Rennae Stubbs is one of many that wants in on the action.

If Djokovic does step up to the challenge, he will have to be ready for a fight. Jackman looks like he's been training.

Djokovic is no stranger to rubbing shoulders with A-list celebrities.

Gerard Butler has been spotted courtside at the US Open plenty of times, as has Jackman, even sitting in Djokovic's player box.

Stay tuned to find out if the match-up ever comes to fruition, but it's certainly caught Djokovic's attention.
