Justin Bieber shares fun behind the scenes photos as he resumes his Justice World tour

Justin Bieber has been sharing some behind-the-scenes photos of his life on Instagram.

Some of the most fun and relaxed shots are from a private performance the singer, 28, put on at a superhero themed party. 

Photos taken by the Yummy singer’s personal photographer, Rory Kramer, were posted early Saturday morning on Instagram, and show Justin taking the stage and posing for various snaps wearing a Spider-Man costume. 

It’s unclear when the photos were taken. Hailey, 25, decided to dress as one of Spidey’s biggest enemies – The Punisher – in a form fitting unitard featuring a skull on the torso. 

The influencer styled her hair in a pony tail using a hair clamp.

In some of the snaps, the Grammy winner seemed to be putting on his own version of The Masked Singer, by wearing the mask while performing on a comic book  themed stage.

Each has been through some medical complications this year. 

In March, the Rhode founder was rushed to the hospital after suffering from what doctors called a mini-stroke, caused by a small blood clot to the brain.  The condition was caused by a small hole in her heart, which has now been closed.

Justin, who was on his Justice World Tour, had to cancel dates indefinitely after he suffered facial paralysis brought on by Ramsay Hunt Syndrome. 

He announced he would resume the tour in July and has posted video from his recent concert in Finland.
