Blake Lively is entering the world of Colleen Hoover.

According to E! News, the 35-year-old actress will play the lead role in the motion picture version of the popular romance book It Ends With Us. She will co-star with Jane the Virgin's Justin Baldoni, who will also helm the film.

On the production crew for It Ends With Us, both the author and the performers will have creative control. According to a press release from Wayfarer Studios and Sony Pictures, Christy Hall (I Am Not Okay With This) and Alex Saks (The Florida Project) are additional producers. Christy Hall is also penning the script.

Blake and Justin are expected to play redheaded florist Lily Bloom and doctor Ryle Kincaid, respectively, with Colleen announcing earlier in the day that she was preparing to reveal those characters' castings. The actor playing Lily's first love Atlas has not been revealed.

"Lily hasn't always had it easy, but that's never stopped her from working hard for the life she wants," reads the book synopsis. "She's come a long way from the small town where she grew up—she graduated from college, moved to Boston, and started her own business. And when she feels a spark with a gorgeous neurosurgeon named Ryle Kincaid, everything in Lily's life seems too good to be true."

This isn't Blake's first time bringing a complicated book character to life. She recently starred as Emily in A Simple Favor (based on the Darcey Bell novel) and, of course, as Serena in Gossip Girl (based on the book series by Cecily von Ziegesar) from 2007 to 2012.
