The Ex: Justin Bieber
We assume Belieb-ers around the world reached for their respective tissues when Gomez swung by the Late Show on March 18 and told David Letterman she made her ex-boyfriend cry. When Letterman brought up how he brought Bieber to tears the last time he was on the show, the happily single Gomez shot back, "Well, that makes two of us!" No longer sniffling, Bieber took to Twitter and responded, "We keep it positive over here."
