Ok we didn't mean to mislead all you Twi-hards out there, but it's that time of year again...Teens for Jeans is back! And Ashley Greene teamed up with cutie Justin Long to show some major love to the campaign to help homeless teens.

So what are they asking? Donate one pair of your jeans to a homeless teen and get a major discount on a brand new pair for yourself! Sounds like a pretty nice deal to us...

Check out their PSA (and outtakes!) above and then, go through your jeans and get donating!
