Shaq and his ex-wife Shaunie O'Neal spared no expense for their daughter's sweet 16 ... and by expense, we mean they dropped almost a mil for the kid.
The O'Neals threw Amirah -- aka Mimi -- an EPIC 16th birthday party Saturday night in L.A. that was fit for royalty -- 'cause the proud parents spent nearly a million dollars on the whole shebang. Yep, you read that right ... $1,000,000.
Sources close to the family tell TMZ Sports that Shaq and Shaunie rented out out the entire rooftop area of the W Hotel in Hollywood, and they gifted Mimi a brand new Mercedes-Benz G-Wagen.
