She admits she was exhausted too.
Selena Gomez has revealed she was taken into hospital because she was malnourished and exhausted.
She was admitted on Thursday last week and it was all very mysterious...
"I'm fine," she says.
"I was just really malnourished, I was low on iron and exhausted."
Spinach sandwiches all round at the Gomez house then?
Usually when celebrities are admitted to hospital 'suffering from exhaustion' you can take a wild guess that they've really 'suffered' from having their drug dealer on speed dial and free access to a titanic amount of booze - but we really can't see that being the real reason that the lovely Selena was admitted, and hope she's feeling a lot better.
Although OBVIOUSLY the interweb rumour mill went into overdrive with speculation that she was up the duff with a Bieber baby.
Right before she was admitted to hospital Selena appeared on Jay Leno and showed absolutely no signs of being ill whatsoever, and now she's back on the road promoting Monte Carlo and looks the picture of health once again!
She must be made of some strong stuff.
