Britney Did Not Go To The Hospital

According to thatotherblog.com & Larry Rudolph, She had a dentist visit, NOT an emergency hospital trip.

But x17 reports that Britney did enter through the emergency entrance:
After less than two hours, Britney is now leaving the Century City Hospital where she arrived with her bodyguard earlier through the emergency room. We're not sure if perhaps Britney was just visiting someone (but entering through the ER?!) or if she herself was admitted. She has now left through the exit in the underground parking garage and appears to be headed home. Whew!
