First it was Beyonce, then Lindsay Lohan, thennn Zac Efron, so who's the latest celebrity to rock Britney's shy-chic fad? Why Sienna Miller of course!
Sienna (above, left) is seen here exiting her car outside a friend's house yesterday afternoon. Britney (above, right) is pictured leaving Koi after dinner in L.A. in mid-August.
Such a trendsetter!
