JAY-Z turns 50 today, and what a 50-years it has been.

Drake celebrated Hov's birthday by prancing around his Toronto mansion, flexing his posh interior as classic while listening to classic JAY-Z tracks like the American Gangster cut "I Know."

"Hov in the house all day, unprecedented," Drake captioned.

We think that's Drake's new mega-mansion in Bridle Path, Toronto

The 21,000 square foot home sits on a $6 million piece of property and features a basketball court, spa, swimming pool, theater room, massage room, hot tub on the roof, custom-made bar and even a museum to display his memorabilia

JAY-Z would approve.
