Roberts founded the online reading community/book club Belletrist, which picked “Didion and Babitz” as its November read. For the literary event celebrating the new book, the known bibliophile wore a playfully sophisticated outfit consisting of a sleek gray ankle-length skirt and a matching triangle bralette over a white short sleeve top.

Hollywood actresses took turns reading previously unpublished letters penned by the late Eve Babitz to others, including Joan Didion.

The exclusive event included a reading of Babitz’s unsent letters by those A-list actors and the book’s author herself, Lili Anolik.
