Selena Gomez, 23, has reacted at the alleged affair with her ex, Justin Bieber, 21, and Kourtney Kardashian, 37, and reports say she's furious.
According to Hollywod Life, the singer was 'devastated’ when the news broke that Justin has been having a 4-month fling with Kourtney that overlapped with when he serenaded her by singing 'My Girl' in the lobby of The Montage Hotel on November 20! That’s when she flipped out and sent him very angry text messages!

In Touch magazine claims Gomez flipped out on Kourtney and reportedly called her up. Then she sent Justin a slew of angry texts.

"Selena texting Justin and expressed how used she felt, since they’d just hooked up around the time of the American Music Awards. But his response was, ‘You know how this business works,’ meaning he did it for the publicity.'" Yikes, we really hope this isn’t true but this is low!
