Simple Life star causes delay to filming

Nicole Richie’s health problems are said to be causing fresh tension with co-star Paris Hilton, 25, on The Simple Life.

According to an on-set source, Nicole, 25, collapsed on location in Malibu last Wednesday – halting filming – and frustrating her co-star and the production team.

Paris, 25 – who didn’t speak to Nicole throughout the whole of last season’s show – was not best pleased.

Series co-creator Jon Murray tells the New York Daily News: ‘There were a couple times when Nicole felt a little woozy and she sat down for a moment, but we continued within five to 10 minutes.’

He explained that Nicole suffered ‘a dehydration thing’ but ‘she’s been doing much better since then’.
