The “Wizards of Waverly Place” star spent a scary weekend in and out of the hospital, giving rise to some bizarre rumors!

Selena Gomez has been all over the media lately, mostly as the girlfriend of teen idol Justin Bieber. This has exposed her to plenty of nasty comments from his tweenage fans that resent an “older woman” of 19 horning in on their territory with the 17-year-old singer. For the last few days, Selena has gotten even more press, but for a more serious reason.

On Thursday night, after taping “The Tonight Show,” Selena suffered a headache and nausea that led to her being admitted to an L.A.-area hospital. She was kept overnight and released Friday, but returned on Saturday. What was wrong? An insider told US Weekly that Selena was felled by a combination of food poisoning and exhaustion, while TMZ reported that she was being tested for blood pressure issues.

These explanations failed to satisfy Bieber’s fans, some of whom jumped to the conclusion that Selena was pregnant with their idol’s baby. Whatever the real cause behind Selena’s problems, the timing is very inconvenient, since she has a new album out and a film, “Monte Carlo,” coming on Friday. This Billboard cover shows the former Disney kid making an effort to establish an adult music career. She’s grown up into quite the hottie, so we hope she succeeds!
