Selena Gomez took advantage of an awkward moment on the Late Show with David Letterman to get a dig in at her ex-boyfriend Justin Bieber.

“The last time he was on, he and I got into a conversation, he said something and I said something, and he said something and I said something and I made him cry,” Letterman said, referring to a sort-of argument he and Bieber got into over tattoos during a previous show.

Without missing a beat, Gomez responded, “Well, then that makes two of us” before giving Letterman a fist bump.
