Celebrity Rehab stars have wet t-shirt competition

Porn star Mary Carey turned up the heat on a shock US reality TV show by participating in a wet t-shirt competition.

The stars of VH1's Celebrity Rehab were given the treat of a barbecue to help improve spirits at the rehab center.

However, some of the stars took it too far, and ended up in the swimming pool, fully-clothed. Seth Binzer was the first in the pool, after being pushed in by Carey. 

She followed in soon after and challenged the rest of the girls to a wet t-shirt competition, much to the dismay of Daniel Baldwin, who went to his room, after complaining to Brigitte Nielson.

Celebrity Rehab is the controversial new reality show that features participants who booze, snort cocaine and smoke drugs.

The series, which started January 10 features Grease star Jeff Conaway, actor Daniel Baldwin, Brigitte Nielson and music star Seth Binzer from 'Crazytown'.

The celebrities are among eight, who agreed to let cameras follow them as they are treated by showbiz doctor Drew Pinsky at a facility in Pasadena, California
