Notre Dame football player Manti Te'o has been all over the news over the last few days because of something that happened to him that's happened to many. Te'o was in a relationship with a woman named Lenay Kekua, who was in a horrific car accident and later died from leukemia. Or so he, and everyone else thought. As it turns out, Kekua was not a real person. The photos Te'o had received from her were of someone else, and "she" may not have even been a she at all. This is a phenomenon known as "catfishing". There's a popular MTV show about it, and the creators talked to CNN about how you can avoid something similar happening to you. Find out more after the jump!
