Mariah Carey throws Bryan Tanaka birthday bash at Tao

Mariah Carey took boyfriend Bryan Tanaka out for his 36th birthday.

The pair were at Broadway hit “Hamilton” before heading to Tao Downtown where Carey rented the private “skybox” — which holds 25 — just for them.

Tanaka posted pics of himself in the room decked out with balloons.

A source told us the balloons weren’t just for decor, but “so other guests couldn’t look in.”

Tanaka wore a Gucci shirt with a tiger on it, and was served a matching cake.
