Selena Gomez: I made Justin Bieber cry

Oh, baby, baby, baby!

Selena Gomez has made ex-boyfriend Justin Bieber cry - and so has late-night TV host David Letterman.

When the "Spring Breakers" star was on "The Late Show with David Letterman" on Monday night, Letterman jokingly told her that he made Bieber cry the last time the singer was on the show.

Her response? "Well, then, that makes two of us."

As for her personal life, the 20-year-old actress said she's "single" and "so good."

But what's not so good is Bieber's recent drama: including a canceled concert, Twitter rants and a report that he was kicked out of a Paris hotel.
