Aren't you forgetting something? Cara Delevingne sees the funny sees after leaving her red knickers on a boat following picturesque cruise in Thailand She was left red faced on Friday after forgetfully leaving a pair of equally red knickers on a boat during her current stay in Thailand. Willowy model Cara Delevingne is currently enjoying a break in South East Asia with close friend Michelle Rodriguez, but the sunshine appeared to go to her head following a picturesque boat trip when she alighted without her underwear. Fortunately for the 21-year-old a well-meaning assistant flagged her by holding the skimpy red knickers aloft – much to her amusement. Cara, who carried an acoustic guitar as she made her way across the jetty in her bare feet, was doubled over as she burst into fits of laughter before making her way back to retrieve them. ‘It was hilarious. The man came off the boat and started waving the red pants in the air,’ an onlooker told The Sun On Sunday. ‘Cara realised her mistake and giggled hysterically.’ Wearing blue floral trousers from Jaded London, that set the star back around £50, and a simple grey t-shirt, Cara looked relaxed and serene. The model is currently taking it easy after a busy round of shows during London Fashion Week – but despite being invited to a string of pre-Oscar parties ahead of the 86th Annual Academy Awards on Sunday evening she opted to spend some down time with Michelle.
