Good one, Selena Gomez! The 20-year-old Spring Breakers actress appeared on Late Show with David Letterman Monday, March 18 and opened up for the first time about her split from 19-year-old heartthrob Justin Bieber earlier this year.

"Last time you were here, you were with a Justin Bieber," host David Letterman said on the show. "That's not going on now."

"No, I'm single," Gomez said. "I'm so good."

"Now, the last time he was on, he and I got into a conversation and he said something and I said something, and then he said something and I said something, and I made him cry," Letterman recalled.

"Well then, that makes two of us," Gomez, with a big smirk on her face, joked.

Cracking up, Letterman applauded the newly single star for her joke by giving her a fist-bump.

Since parting ways in late-December after over two years of dating, the exes have only addressed their split in cryptic references through song. The "Who Says" singer told Letterman that she isn't dating anyone "yet."
