Ashley was so sick last year that she told her mother she was ready to just give up.
The teen came down with a case of meningitis so severe that she missed her quinceañera, or 15th birthday, a moment that is celebrated as a girl's coming of age in Hispanic culture.
But Ashley pulled through. And she finally celebrated the milestone with the help of none other than Justin Bieber.
Bieber surprised Ashley on an episode of Fox's "Knock Knock Live," a show in which celebrities grant people's wishes, completely by surprise.
A clip posted to YouTube on Tuesday shows Bieber bringing Ashley to tears after rapping at her door.
He then whisks her to the quinceañera party that she never had a chance to celebrate while she was sick.
The pair even shared a dance to his song, "Pray."
The encounter clearly had an effect on Bieber, if this tweet was any indication.
It's the second time recently that we've had a chance to see the pop star's sensitive side, rather than more bad boy antics.
On Saturday, Bieber pumped up the Canadian team at the Special Olympics World Games with a chant of, "Let's go Canada!"
But Bieber's good deeds don't end there. He previously won the Champ of Charity Award at the Young Hollywood Awards, in recognition of his record-breaking efforts to grant wishes through the Make-a-Wish Foundation.
He has also helped to raise money for victims of Typhoon Haiyan in the Philippines.
You make Canadians proud with these gestures, Justin. Keep it up.
