Janice Dickinson Janice Dickinson

I'm a Celebrity ... Get Me Out of Here! contestant Janice Dickinson was rushed by ambulance to the reality series' on-site medical facility over the weekend, says an NBC spokesperson.

Dickinson sought treatment for an undisclosed condition — and not necessarily any of the myriad things (bronchitis and hunger, for example) viewers have seen her complain about on-camera thus far, a production insider tells TVGuide.com.

The former supermodel's personal publicist had yet to speak with Dickinson since the incident, but told us, "Janice loves her fellow cast mates, and is having a jolly old time in the jungle."

Dickinson went to the same facility that treated Heidi Pratt last weekend, before she was checked into a hospital in San Jose, Costa Rica, with what doctors ultimately diagnosed as either a gastric ulcer or gastritis. Pratt — and husband Spencer — ultimately left the show.

Dickinson's own fate with I'm a Celebrity will be revealed during Monday night's two-hour program, says our source.
