It’s 28/12 which means Happy Birthday Sienna Miller! We’d like to send her big birthday wishes, and hope she spends a special day being spoiled by her loved ones.

It’s been a fantastic year for Sienna both personally and professionally, with the birth of her daughter, and the success of The Girl and her Golden Globe nomination for it. The year ahead will hopefully be just as positive, starting off with the Golden Globe Awards themselves in the middle of January, and then hopefully the release of several films throughout the year. We are continually intrigued to see what Sienna will do with her career next, and wish her the absolute best in every part of her life.

Feel free to leave your birthday wishes for Sienna by posting a comment below.
