The actor-writer-artist, 37, has penned a short book about friend Lana Del Rey, Penguin Random House recently revealed on its website.
Titled Flip-Side: Real and Imaginary Conversations with Lana del Rey, the 100-page book was co-written with New York Times best-selling author and previous collaborator David Shields, and will be released in March of next year.
This isn't the first time Franco has zeroed in on Del Rey, 30, initially writing a poetic ode to her in V Magazine, seemingly beguiled by her unapologetically "weird" personality.
"The only difference between Lana and me is her haunting voice. That carries everything. The voice is the central axle around which the spokes of everything else extend," he wrote in the piece titled "Shades of Cool". "My axle, like her voice is for her, is my acting. Out of it, I do everything else."

Franco ended the piece with a quote from Del Rey, which now proves he's a man who can accept a challenge: "I wanted to interview Lana for a book and she said, 'Just write around me, it's better if it's not my own words. It's almost better if you don't get me exactly, but try.' "
