Carly Rae Jepsen Performs at Justin Bieber's Birthday Bash!
Carly Rae sang the song that helped bring her to fame, "Call Me Maybe", which has gone viral over the last few weeks thanks to Justin and his friends.
We love this video because it gives us a small taste of what it was like to attend the pop-star's big birthday!
Our favorite part is watching Justin Bieber and gal-pal Ashley Tisdale be a little goofy as they sing and dance along!
Watch the video below to see the live performance and let us know what you think!
