Bonnie Says: Selena Gomez, Kendall Jenner rekindle friendship despite Justin Bieber

Selena Gomez and Kendall Jenner -- you two are showing such maturity by making up after breaking up over Justin Bieber. You both have smartly come to the conclusion that Hollywood is a small world, and when you have similar friends and similar interests, you're bound to keep bumping into each other. That's why it's great that you both have decided that you're not going to allow him to get in the way of what had been a blossoming friendship.
