The green bikini also showed off the model's deep tan to optimum effect.
But there was no sign today of Sand's 25-year-old husband Laurent Homburger, following recent reports that the pair were getting a divorce after just one year of marriage.
The New York Daily News reported that Sand was seeking an end to the marriage after a turbulent few months which saw her file a restraining order against Homburger after both were arrested following an argument in May.

They have three children together Alexandra, 13, Victoria, 11 and Isabella 10.
