Justin Bieber's 'Mistletoe' Girlfriend Revealed!

Meet the lucky girl — Allie Williams — who got to kiss Justin Bieber in his ‘Mistletoe’ music video!

We’ve been dying to know the lucky girl who got to be Justin Bieber‘s girlfriend in his “Mistletoe” video…thankfully, the video’s director, Roman White, has revealed her name and HollywoodLife.com has exclusive details!

“We were casting, and everything had to be very secretive, so we were literally casting these girls, we couldn’t tell them who it was, and we couldn’t tell them any of the stuff, because we were trying to keep this shoot as much under wraps as we could…So this girl came out, her name is Allie Williams, and she was my number one pick from the minute she walked in,” Roman explained to MTV after the video premiere Oct. 18.

He added, “So I ended up casting her [as Bieber’s love interest], and we went and did the fitting, and I got permission from my producer. … I told her who it was, and she was really excited to be in it, to say the least.”

After doing some digging, we discovered Allie goes to Harpeth High School in Nashville, Tenn. and is slated to graduate in 2013. If we’re doing our math correctly, that makes Allie 16 or 17 years old, which is perfect for Justin…too bad he’s taken!
