(Photo: Getty Images) Actress Olivia Wilde is on the cover of Glamour's September 2014 issue, and inside she is photographed breastfeeding her 3 month old baby, Otis (daddy is Jason Sudeikis).

Olivia says in the magazine: "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. Breastfeeding is the most natural thing..." She did add, however, that she doesn't normally look like this when she is breastfeeding.

This is a shot from the mag posted by Olivia on Twitter...
