Sienna Miller is a Pink Bikini Beauty

Sienna Miller shows off her bikini body on the beach as she and some girlfriends spend time together in Barbados on Monday (January 4).

The 28-year-old actress and her friends rode on an inflatable float, and Sienna took a dip in the ocean to cool down!

Former flame Jude Law met up with Sienna on the island before New Year’s, but it looks like today was a girls’ day out!
