Diane Keaton Wore the Chicest Fall Trends in Justin Bieber's Music Video

Whenever Justin Bieber debuts a new music video, it's bound to go viral. But his newest one happens to have some unexpected crossover appeal thanks to a cameo by the one and only Diane Keaton. The 75-year-old actress isn't the first name you think of when you consider who's in Bieber's fan base, but this charming new video just proved that they're quite the dynamic duo.

Keaton stars as Bieber's grandmother in the poignant new music video for "Ghost," which is about healing from grief. Keaton revealed in an interview with Vogue that she brought her own clothes to wear in the video, including a fabulous plaid Gucci coat. "That coat is really killer for me. It's my favorite," Keaton said. "A coat is the greatest thing in the world for a person like me who's kind of odd. Let's face it: I'm willing to accept the fact that I'm a little odd." Scroll down to watch the video and to shop Keaton-inspired pieces.

Associate Director, Fashion News

Erin got her start as a Who What Wear intern over 12 years ago—back when the site only published a single story per day. (Who What Wear has since increased that number twentyfold.) She graduated magna cum laude from USC, which is how she ended up moving to Los Angeles from her hometown of San Diego. In college, she also interned at Refinery29, where she was promoted to editorial assistant and then assistant editor. After nearly three years at R29, she came back to WWW in 2016, where she currently holds the title of Associate Director of Fashion News (as well as the unofficial title of resident royal expert—in case you haven't noticed her numerous Meghan Markle and Kate Middleton stories). She spends her days trying to incorporate her idols, Anna Wintour and Roger Federer, into as many stories as possible. Outside of work, she loves tennis, classic rock, traveling, and smothering her dog with affection.
