LONDON: Katie Price and cage fighter Alex Reid have embarked on a 48-hour sex marathon in Marbella, Spain, emerging from their bedroom only to cavort semi-naked in the pool.

Katie Price and her new lover have vowed to spend 48 hours in bed.

The former glamour model - known as Jordan - and cage fighter Alex Reid arrived in Marbella, Spain, on Sunday (02.08.09) and have only emerged from their luxury villa to cavort topless in the pool.

A source said: "Katie and Alex are all over each other and have told their friends they won't be leaving the villa. Katie said her sex life with Reid is wild.

"They are either in their bedroom with the doors shut or in the pool. They're both obsessed with sex and are really into each other. Jordan loves experimenting and so does Alex."

Katie's friends fear the model's estranged husband Peter Andre could use the intimate photos of her and Alex on holiday to discredit Katie in the custody battle for their children - Junior, four, Princess Tiaamii, two, and Katie's seven-year-old son Harvey, from a previous relationship.

A source said: "Peter will be furious about these holiday photos. If he decides to attack Katie in court in any future custody battle, then these are the types of images that could be very damaging to her cause."
