Justin Bieber appeared in "Episode 2" which aired on July 28, 2015. Justin surprised a fan was named Ashley Contero; she had been struggling with illness. Justin bought her a dress and took her on a date and to an event that took the place of her quinceñera, which she missed due to her illness. And after the segment, Bieber and Seacrest gave her mom a check for $10,000 to help pay the medical bills.
And that wasn’t all: Justin also knocked on someone else’s door: a single father named Nakia who has a son with downs syndrome. Bieb showed up at his church “just to give them some love and see what I can do to help,” and gave him a check for $50,000.
