Megan Fox was spotted last weekend frolicking on a beach during a Hawaiian vacation with her husband Brian Austin Green.

Catching rays, the Tranformers star looked like she had lost a few pounds since her curvaceous figure made her one of the hottest stars in Hollywood.

Wearing a tiny black polka dot bikini the 24-year-old star revealed a toned physique.

Fox was crowned with the title the "the sexiest woman alive" by men's magazine FHM in 2008 and 2009.
