Justin Bieber's Salt Lake City concert was delayed this Saturday, but he had a great excuse to be late.

He was visiting Millie Flamm, a 7-year-old fan and leukemia patient who was too sick to attend his show due a recent relapse.

Justin, who came under fire when TMZ posted photos of him smoking what appears to be marijuana, performed his hit song "Baby" for his young fan and even gave her his guitar pick.

He also gave Millie a kiss on the cheek and shared this sweet photo of them on his Instagram, saying: "Look at this bundle of joy..I love her."

This is one photo we definitely approve of!

Justin's visit with Millie happened after a social media campaign from Millie's family and friends, which caught the Biebs' attention.

Good job, Justin!
