Selena Gomez stopped by the “Late Show,” and David Letterman wanted to know all about the men who have recently been in Selena’s life. First up, ex-boyfriend Justin Bieber. Dave said that the last time Bieber was on the show, Dave accidentally made him cry. “Well then that makes two of us,” Selena quipped. Dave had to give Selena a fist-bump for that one. They also talked about Selena’s ‘Spring Breakers’ co-star James Franco, who she said was “creepy” on set.
