Olivia Wilde

Olivia Wilde is keeping Harry Styles close to her heart while he's away on tour.

On Thursday, the actress and producer, 37, was spotted out and about in Los Angeles wearing a black hoodie embossed with the words "Treat People with Kindess," which is the the title of a song and music video released by Styles earlier this year.

Wilde paired her hoodie (which is available to shop now on the singer's website for $54.99) with black leggings, black sneakers and orange-tinted sunglasses.

The subtle show of support comes after the Booksmart director attended Styles' Love on Tour concert in Las Vegas in September, a concert goer told E! News.
