There are few actresses in Hollywood that truly embody the classic movie star charm. Julia Roberts, who has solidified herself in our hearts and on our television screens for decades, is one of those special people. Her smile radiates through her, and subsequently through us, in a magical way that always leaves us craving her feel-good vibes. She's smart, hilarious, gorgeous, and in the purest sense of the word, a screen siren. Now, on her 47th birthday, we're celebrating every time we fell (hard) for America's sweetheart.
