She shot to fame as an on-screen princess, but Anne Hathaway came face-to-face with the real deal on Tuesday.
The Princess Diaries star looked delighted to meet Charlene of Monaco, showing off her megawatt smile as the pair posed for the cameras together.
Charlene had donned a beautiful floor length Christian Dior gown for the Princess Grace Awards Gala in New York.
Featuring floral embellishment and dramatic draping, the dress was stunning on the statuesque blonde.
Meanwhile, Anne spiced up her simple champagne-hued, embellished shift dress with a bright red lip and large drop-diamond earrings.
Charlene was joined by husband Prince Albert of Monaco, who is vice chairman of the foundation which is dedicated to helping emerging talent in dance theatre and film.
Other famous faces included music and film legend Julie Andrews and fashionista Olivia Palermo.
