Looks like Jason Sudeikis's little boy is his biggest fan! Olivia Wilde [1] took to Instagram on Thursday to share an adorable picture of the couple's son, Otis, watching Jason's interview with Jimmy Fallon [2] 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 [3] 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 [4] from this past Winter. In June, she also gave another glimpse of her son with a fun snap of their park date [5] in NYC.
