Exhale, Justin. Selena Gomez is expected to make a full recovery from her recent illness, with plans to perform in Santa Monica on Monday, E!News reports. The singer was admitted to a Los Angeles hospital on Thursday after complaining of nausea and a headache during an appearance on The Tonight Show. While gossip-mongers would like to believe it was the result of something more salacious (pregnancy rumors abound!), the 19-year-old was reportedly treated for a combination of food poisoning and exhaustion. (Are we talking exhaustion exhaustion? Or, Lindsay Lohan-style exhaustion?) After seeking additional treatment over the weekend, Gomez will return to the stage for her Santa Monica mall performance, previously scheduled for Friday. Looks like all those prayers and #getwell Selena Twitter messages worked! Once again, bow down to the power of the Internet.
