Meanwhile Jamie opted for denim shorts and a blue shirt unbuttoned to the navel.
Earlier in the day the 35-year-old lazed on the beach with Hince, who's a guitarist with The Kills.
And it seems she is certainly not giving up her smoking habit for the New Year, as she was spotted enjoying a cigarette as she wandered down to the beach.

Kate and Jamie had been due to fly out on Boxing Day for their annual break.
They spent last New Year in Thailand, and Kate used to holiday there with her former lover Pete Doherty.
But their trip was postponed as Kate was so hung over following her Christmas excesses that Hince refused to let her travel.
They eventually left two days later. Losing their first-class flights cost Kate an estimated £20,000 - a drop in the ocean to the multi-millionaire.
