I had a math test on the day of my 11th birthday, but this is cool too: Room and Wonder star Jacob Tremblay, a.k.a. everyone’s favorite kid actor and Star Wars superfan, turned 11 yesterday and celebrated it as… Eleven. With his head cropped onto Millie Bobby Brown’s now-iconic pink dress, Tremblay makes the case for dressing up as Eleven for Halloween (again).

“Today I am #Eleven!!! Thanks for all the #birthday wishes!!!” captioned the birthday boy.

The Sharjah International Children’s Film Festival also threw a birthday party for the young star, and the theme was extra-appropriate. This year, Tremblay already met his hero Mark Hamill and celebrated Star Wars Day with Padme Amidala herself — oh, and named his puppy Rey! – but that doesn’t mean he can’t have a BB-8 cake.

“Thank you @SharjahICFF for a great birthday party & everyone for making me feel so special!” Tremblay captioned his second birthday post, “#feelingblessed #choosekind.”

Happy birthday, Jacob! Keep being the best superfan in Hollywood!

Tremblay’s next film, Wonder, which also stars Julia Roberts and Owen Wilson, arrives in theaters on Nov. 17.
