Better behaved than I've ever been at the dentist. Guess they gave him the good drugs. 😁

Aww! Olivia Wilde took to Instagram on Monday, March 28, to share an adorable photo of her son Otis’ recent trip to the dentist.

In the pic, the 23-month-old tot — who Wilde, 32, shares with fiancé Jason Sudeikis — beams ear to ear as he patiently waits in the dental chair. “Better behaved than I've ever been at the dentist,” the actress wrote alongside the sweet snapshot, joking, “Guess they gave him the good drugs. 😁”

Otis certainly has a lot to smile about. The little guy turns 2 on April 20, and his mom has a very exciting Beyoncé-themed birthday bash planned for him.

“It’s gonna be a Beyoncé listening party appreciation dance-off,” Wilde revealed during a March 10 interview on The Ellen DeGeneres Show. “His love for Beyoncé has really hit a fever pitch and I approve, of course, but it’s intense.”

During Wilde’s appearance, DeGeneres, 58, surprised the Vinyl star with a set of party decorations for Otis’ upcoming Bey-day celebration.

Asked how her only child’s fixation with the “Formation” singer started, Wilde explained: “Well, he, you know how a lot of moms have on their iPads, like a kids’ show, like an appropriate-for-kids program, like an Elmo and such? I didn’t and we were on an airplane and I needed, as many of you know, a distraction tool immediately, and all I had was all of Beyoncé’s videos from her last album. And so I just put those on for him.”

From insanely cute infant to die-hard Queen Bey fan, Otis has grown so much already. In summer 2015, Wilde posted a throwback pic of herself, Sudeikis, 40, and their onesie-clad baby in his younger days.
