Justin Bieber for PETA Kids

Justin Bieber always makes sure that his fans know how much he cares about them. Whether surprising them on TV, responding to them on Twitter, or even dedicating a song to them to let them know how much they mean to him, Justin puts his fans first. Now, Justin is teaming up with PETA Kids for the second time to send a message that he hopes you will take to heart—if you need someone to make "U Smile," adopt a homeless animals from your local animal shelter!

Every year, more than 7 million animals enter animal shelters, and 3 to 4 million of them must be euthanized because there are not enough good homes for them. The next time that you're looking for a furry friend to be part of your life, don't support pet stores or breeders—adopt!

If animals (and Justin Bieber!) make "U Smile," help end animal homelessness by always adopting and never purchasing animals from pet stores or breeders and by spaying or neutering your animal companions.
