Gwen Stefani shared a moment she'll never forget during her concert on Wednesday -- all thanks to one young fan.
The 46-year-old singer took a break from performing at the Perfect Vodka Amphitheater in West Palm Beach, Florida, when she noticed a sign in the crowd ahead of her, taking a moment to read it out loud.

"My son was bullied from 1st to 5th grade," Stefani read, letting out a "What?" of disgust.
"He'd come home every day upset, but he'd go to his room and listen to your music and smile…" she continued. "Get up here right now! Right now!" she yelled, before tossing the note aside, and welcoming the young boy, consumed with tears and emotion, onstage.
"Where's your mom?" Stefani mouthed to her young fan as he pointed her out in the crowd, before posing for a picture.
And of course he couldn't leave with a little Gwen Stefani pep talk and a huge hug from his favorite singer.

Stefani, a mother to three boys of her own, explained the significance of the sweet moment a day later on her Instagram.
"About 3 years ago when things were hard in my life I prayed to God everyday that I could get a chance to use my gift that God gave me and make a difference in some way in this world," she wrote. "Last night this little guy was the answer to my prayers #zerotoleranceforbullies #onelove #thisiswhatthetruthfeelslike."
"King and I cry [sic] so hard when we saw this last night!" she added on Twitter.
It's been an emotional time for Stefani. Just last week, the "Misery" singer broke down when recounting "the hell" of her split from Gavin Rossdale.
"I wasn't trying to start a relationship," she told the radio host of boyfriend Blake Shelton. "I was just trying not to die."
