Andrea Russet is the cool chick with those random and funny YouTube videos. But besides, gaining millions of subs online she's also doing good.
She's joined the Thirst Project to help give thousands of children around the world access to clean water. Pretty big deal right? Well, that's why she's celebrating it in a big way. Andrea's bringing in her 21-st birthday with one lucky fan -- and it could be you!
All you have to do is donate through Andrea's Prizeo page and you'll be entered to win two tickets to a Demi Lovato and Nick Jonas concert with Andrea on your arm. It takes just $25 dollars to give someone clean water for life!
