If both Justin Bieber and Selena Gomez start crying rivers, we're going to need to initiate a flood watch.

Remember back in November, when JB sang Justin Timberlake's "Cry Me a River" right after The Big Split with Selena Gomez? Selena just returned the favor.

At a UNICEF event on Saturday, January 19, Selena sang "Cry Me a River," telling the audience, "This song definitely speaks to me." Maybe it tells her, "Two can play this game." Justin and Selena have reconciled and split a couple of times since that first bomb dropped, but now it's feeling over over. Unless maybe they bond over their (sad) new theme song?

Check out Selena's version here, and Justin's version here. Who wins this crying game?
