"Not just Kylie, there were pictures Kendall sent him too," a source had told the Website. "But that wasn't the reason that Selena broke up with Justin. She saw messages and pictures from other girls that made her a 100 percent sure that he's been cheating on her since they got back together. She said she was only giving him one more chance and that was it."

Gomez and Bieber were quite open about their relationship when they hooked up for the first time they seem to be more cautious of their privacy now.
