Heidi Montag hospitalised in Costa Rica

Heidi Montag has been hospitalised in Costa Rica, reports say.

According to E! Online, the Hills star had fallen ill during her and husband Spencer Pratt's stay in "isolation" from the rest of the I'm A Celebrity...Get Me Out of Here! cast.

Pratt's sister Stephanie revealed the news on her Twitter page and has blamed NBC for going "too far" with the newlywed couple.

She said: "Heidi was rushed to the hospital and has an IV in her arm after being locked in a dark room for 3 days w no food or water. Pls pray she will be ok…Her family is flying out to see her in the hospital."

NBC exec Paul Telegdy said recently that the "insincere, lazy, entitled" Pratts had to endure a period of "isolation" and vowed that the couple would "really bare their souls".
