Hello there, little Otis! Three months after Olivia Wilde and Jason Sudeikis’s baby arrived, the first-time mother showed her adorable son’s face to the world by posting an adorable snap of the little one (who was born April 20) on Instagram. The pair seem to be enjoying some time together while taking a walk in the great outdoors, and kept things casual for the outing—the actress wears a sweatshirt that reads “Rock and Roll” (perhaps a nod to her next project, Martin Scorsese and Mick Jagger’s untitled rock ’n’ roll pilot for HBO) while Otis looks sweeter than ever in a gray hoodie with animal ears. The baby boy is seen peeking over his mom’s shoulder as she holds him, revealing his beautiful dark brown eyes. Wilde captioned the picture, “Rock and roll, baby.” So cute!
