Catherine Zeta Jones sunbath in beautiful brown bikini at Portofino

Catherine Zeta-Jones continued to make the most of her European vacation with husband Michael Douglas on Friday, lounging on a luxury yacht in Portofino, Italy in a barely-there bikini.

The 41-year-old Welsh actress, who has been enjoying a month-long Mediterranean cruise with her husband, looked absolutely sensational, showing off her swerving curves in a bronze string bikini, which was embellished with stylish hardware. Her dark hair was pulled back under a chic scarf.

The couple has been spotted all around the Italian and French Riviera over the last week, spending time with rocker Jon Bon Jovi in Antibes on Wednesday.
