XOXO, it's Julie Andrews.

The iconic actress is joining the cast of Shonda Rhimes' upcoming Netflix show. The untitled, eight-episode period drama is an adaptation of Julia Quinn's bestselling Bridgerton novel series.

The story takes place in the sexy, lavish and competitive world of London high society circa 1813. According to Netflix's description, the series whirls from the glittering ballrooms of Mayfair to the aristocratic palaces of Park Lane and beyond, and unveils a seductive, sumptuous world replete with intricate rules and dramatic power struggles, where no one is truly ever on steady ground.

Andrews will be the voice of Lady Whistledown, an anonymous and mysterious gossip writer whose mix of social commentary and scathing insults send Regency London into an all-out frenzy.

At the heart of the show is the powerful Bridgerton family. Comprised of eight close-knit siblings, this funny, witty, daring and clever group must navigate the upper ten thousand’s marriage mart in search of romance, adventure and love.

Andrews, of course, is the legendary star of "Mary Poppins" and "Sound of Music." She has stuck mostly to voice work in recent years, lending her distinctive timbre to "Aquaman" and "Despicable Me 3."
