For an actress without any implants to show off, Sienna Miller is officially one of the least inhibited stars around. Our friends at Egotastic have caught the sweet talker revealing her naughty bits in the past, and earlier this year we learned about her habit of getting busy in restaurant wine cellars. And now, it seems the ocean's ability to remove her bikini top led Sienna to turn a day at the beach into an opportunity to pretend she was on a nude one for a while, chit chatting topless and waiting longer than one usually does to fix a loose suit.
