Looks like Jason Sudeikis's little boy is his biggest fan! Olivia Wilde took to Instagram on Thursday to share an adorable picture of the couple's son, Otis, watching Jason's interview with Jimmy Fallon from the dressing room. The actress wrote, "Cheering Dad on in the dressing room at @fallontonight for his awesome new movie Sleeping With Other People which is very very funny and everyone should go see it Sep 11th!!" The sweet snap comes just a couple months after Olivia posted a frame-worthy throwback photo of her family from this past year. In June, she also gave another glimpse of her son with a fun snap of their park date in NYC.
