Selena Gomez: I'm 'Feeling Much Better' After Hospital Stay

You can all breathe a sigh of relief now: Selena Gomez is A-OK! The starlet has been hospitalized twice over the last few days, and today she took to her Twitter to tell fans she's "feeling much better." 

She's even well enough to perform tonight, after rescheduling the performance from Friday. "Feeling much better, thank you all for being so understanding. Can't wait to see you all today at Santa Monica..." she wrote.

Still no word on what was ailing the 18-year-old -- sources have claimed everything from food poisoning, fatigue, and blood pressure issues were to blame.
