She may be American, but Meghan Markle knows the British national anthem!
The future royal was spotted at the Commonwealth church service at Westminster Abbey on Monday. As Queen Elizabeth II arrived at the Abbey, the 36-year-old actress and humanitarian flawlessly belted out the words to "God Save the Queen," as she sang along with the congregation and her fiance, Prince Harry.
The event marked Markle's first public event with Her Majesty, and she looked the part of a bride-to-be, pairing a cream-colored Amanda Wakeley coat with a white Stephen Jones hat and navy heels. The stunning brunette wore her hair down in cascading loose curls along with minimal makeup.
Prince William, Kate Middleton, Prince Charles, Camilla Parker Bowles, Sophie, the Countess of Wessex and more members of the royal family were also on hand at the large interfaith gathering, where former One Direction heartthrob Liam Payne performed a cover of John Mayer's "Waiting on the World to Change."
Markle, who got engaged to Prince Harry in November, intends to become a British citizen following their royal wedding on May 19.
