Heidi Pratt, formerly The Hills Heidi Montag, has reportedly been rushed to hospital in Costa Rica with stomach problems.

The reality TV star has been appearing with new husband Spencer Pratt on the US version of I’m a Celebrity…Get Me Out of Here since last week but is said to have been whisked from the jungle setting to a hospital after “convulsively throwing up”.

A source close to the show claims she’s been diagnosed with a gastric ulcer as a result of feeling “tortured” on the celebrity-dare show: “It’s not too serious but she regrets returning to the show.”

Heidi and Spencer walked out of the series on Day 4 but returned on Day 6.
