Concern is growing for Californian-born supermodel Caprice Bourret after conflicting reports over her health and state of mind. British newspaper The Sun claims the blonde beauty has become the latest in a long line of celebs to check herself into rehab at London's exclusive Priory centre, where she is undergoing addiction therapy and counselling for depression. However, the Daily Mail insists her situation is far more serious and the 35-year-old is on suicide watch in hospital after taking a suspected drugs overdose. A hospital source tells the newspaper Rod Stewart's ex was admitted "in a terrible state," adding, "Thankfully she is stable now, but clearly we're worried about her." Bourret hit the headlines last August (06) when she lost her license for 12 months following a drink driving conviction.
