A show spokesperson said: "As a precautionary measure Olivia needed to leave the jungle to undergo medical checks. "Unfortunately, the medical team has advised that it is not safe for Olivia to return to camp as there needs to be further investigation. "She has been absolutely brilliant and she'll be very much missed on the show." After enjoying a meal with radio DJ Chris Moyles, the pair were then given their first challenge of jumping out of a helicopter at 10,000ft. "Oh my god I'm crying, that's the most amazing thing I've ever done, ever," she exclaimed after landing on a beach. "That is incredible. Top 10 experience of my life. Just amazing." It was only when they joined Boy George and Scarlette that they finally realised that being VIPs wasn't as good as it sounded, unsurprisingly - and that they were actually 'Very Isolated People' marooned on an island. The four stars were due to take part in the very first Bushtucker trial, which is set to air tonight. It is not known whether Olivia's medical issues occurred after the trial. Attwood's early exit means she now holds the joint record for shortest time in camp, along with EastEnders actress Elaine Lordan who withdrew after just a day in 2005 when she fainted twice in one day.
