Olivia Wilde was photographed breastfeeding her baby son Otis for a high-fashion shoot in US Glamour's September issue.
While the beautiful photos of Olivia and Otis suggest he was a natural in front of the camera, the 30-year-old actress tweeted the following revealing what really happened behind-the-scenes.
Feeding time with a newborn baby, no nappy and a Roberto Cavalli dress? That's just asking for trouble.
But Olivia's #boobfood humour makes it clear she's not shy about sharing the details on motherhood.
"Being shot with Otis is so perfect because any portrait of me right now isn't complete without my identity as a mother being a part of that," she explained in her interview with Glamour editor-in-chief Cindi Leive.
"Breastfeeding is the most natural thing. I don't know, now it feels like Otis should always be on my breast. It felt like we were capturing that multifaceted woman we've been discussing - that we know we can be.
"You can be someone who is at once maternal and professional and sexy and self-possessed. [But] I mean, I certainly don't really look like that when I'm [typically] breastfeeding. And there's usually a diaper involved."
