rumored to be starring in the bondage flick

As part of her promotional tour for her very adult new film "Spring Breakers," Selena Gomez stopped by "The Late Show" to have a little chat with David Letterman -- and apparently, talking about her ex-boyfriend Justin Bieber was not off-limits. "The last time he was on ... I made him cry," Letterman said. To which Gomez replied: "Well, then, that makes two of us." Oh, snap. That one earned a fist-bump from Letterman, so we're guessing Bieber won't be on "The Late Show" any time soon! Gomez isn't feeling bitter over the break-up, though. She says, "I'm single, I'm so good!" when asked about her current love life. At least the split has inspired some sassy new dance choreography!
