Princess Anne celebrated her upcoming 75th birthday with a royal portrait - and while she looks stunning, her hair change is turning heads. In the photograph, released by Buckingham Palace on Friday, August 8, the princess royal, 74, smiled for the cameras while standing beside her husband, Vice Admiral Sir Tim Laurence. Anne, who turns 75 on Friday, August 15, traded out her iconic voluminous bouffant hairstyle in the portrait for an elegant, twisted bun updo. She wore a diamond Festoon Tiara that sat perfectly atop her head and was tucked into the twist of her hair.
