Hailey Bieber Cheers For Justin Bieber 

Hailey Bieber showed support to Justin Bieber as he returned to the stage Sunday at Lucca Summer Festival in Italy to resume his Justice World tour following health struggles.

The Rhode mogul shared Justin Bieber video footage while performing, on her Instagram Story, and wrote, "One thing I know for certain is you can't keep this guy down..."

In a video posted by Justin Bieber, Hailey could be seen hanging by his side as he celebrated his return to stage with his team.

"We're back. What a great, great evening. Wow. I love you guys," Justin Bieber says. "I'm just so grateful to be back. I love each and every one of you so much ... Let's go. Let's go kill it."

Bieber had postponed several of his shows on the tour due to his diagnosis with Ramsay Hunt syndrome, which caused him facial paralysis.
