Hugh Jackman may have turned 50 recently but the homegrown Hollywood star works hard to keep his physique in top form.

The Aussie actor-singer-dancer-producer recently posted a short video to his Instagram account showing him working on his biceps at a gym.

But it wasn't an ordinary workout.

Beside Jackman was an unusual gym buddy — animated Playmoji version of rapper Childish Gambino.

"Come on man, let's go!" Jackman can be heard saying as he glances at his Playmoji partner.

The brief video was tagged with the Instagram account for a New York-based personal training firm called The Dogpound, which describes itself as "results driven personal training".

Jackman, who wears a Dogpound T-shirt in the video is possibly using the gym to get in top shape for his upcoming world tour.

While Jackman used a hashtag to tag Gambino, it's not known if the rapper is on-board with the joke.

Jackman performs a few bicep curls showing off impressive muscles while the much smaller and shirtless animated version of Gambino — whose real name is Donald Glover — dances and gyrates strangely beside him.

Gambino, 35, who is actually 5-foot and nine inches in real life, recently made a video for Google Pixel 3 promoting the Childish Gambino Playmoji in which twin versions of himself dance together.

Gambino, who is also an actor, comedian, singer-songwriter and DJ scooped the pool at the Grammy Awards with This is America winning for Song of the Year and Record of the Year as well as Best Music Video and Best Rap/Sung Performance.
