The Lazarus Effect star Olivia Wilde shared a rare shot with 13-month-old son Otis via Instagram.

“#BrooklynBridgePark #PleaseTouchTheArt #TheStokes,” the actress, 31, captioned the fun photo.

Olivia and her fiancé, SNL alum Jason Sudeikis, celebrated their firstborn child’s milestone birthday in April.

“We had an awesome celebration and especially in the midst of bringing Body Team 12 to the festival, I felt even more fortunate to be able to celebrate with Otis and be able to allow him to have this happy, happy day,” Olivia said of her son’s first birthday bash.

She added: “I just feel so lucky and I am so overwhelmed with happiness.”
