Just when did Selena Gomez start drinking so heavily that she ended up with a hangover? Apparently it was on her 20th birthday, if you believe Yahoo! omg!:
Of course, if you believe anything you read by a Yahoo! staffer, you’re naive or gullible. Or you just haven’t been reading Terribly Write. The truth: Ms. Gomez just turned 21. That means she is starting her 22nd year, not her 21st. Yahoo! writers have never been good at basic arithmetic.
