It’s starting to be difficult to keep track of all of Justin Bieber‘s different charities and humanitarian efforts. The teen pop star (and now movie star) has already helped out with PETA, visited ailing children at hospitals, and donated his hair to benefit an animal charity. Now, Bieber has moved on to clean water.

Bieber turns 17 this Tuesday, and is looking to do more than just spend some time with his now official girlfriend, Selena Gomez. Bieber is participating in mycharitywater.org‘s efforts to raise money in order to bring clean water to people in developing countries.

If you visit Bieber’s mycharity page titled “Justin’s 17th Birthday,” you can donate money in any amount and 100% of it will go toward clean water projects. Since it is Justin’s 17th, the star is suggesting that people choose a donation of $17. High rollers can opt for $170, but if you’re really rich (or very poor) you can choose any other amount you want.

In Bieber’s own words: “This year, I really want my birthday to be all about helping others. Instead of asking for gifts, I’m asking friends, family and fans to consider donating $17 for my 17th birthday to help make a change.”

Yet another “dude, that Bieber kid is kind of awesome” moment for Justin. What’s next, he saves a litter of puppies from a burning building?
