Just when you thought Justin Bieber couldn't get any cuter . . .
Though he normally sings to teenagers (and almost-teenagers) during his concerts, Bieber brought a lucky 9-year-old onstage in London this weekend.
At a secret concert held Saturday -- the day after he took Wembley Arena by storm (and hung out with Kelly Clarkson backstage) -- the Canadian pop star brought a fan named Leah onstage so he could serenade her with his hit track "One Less Lonely Girl."
Leah had reportedly spent 24 hours waiting to see her idol -- and it was her birthday! Though Bieber gave her a a personal serenade and a dozen roses for her trouble, Leah also had a gift ready for him. Even at age 9, she made sure he knew of her affection.
"Did you give me your phone number?" Bieber asked with a grin, reading the message she wrote on a blue gift box.
The "Boyfriend" singer tweeted Leah's video (presumably filmed by a relative) soon after the show, along with the message: "from 80,000 in Wembley to a club gig the next day...this is why we do it. for the fans. LOVE YOU."
A day later, Leah was still over the moon.
"Still can't believe that Justin tweeted my video from the secret show ahhhhhh," she tweeted.
The secret gig was reportedly part of a TV special Bieber is filming.
