For Offset's 29th birthday last year, his famous wife Cardi B bought him a rare Lamborghini Aventador SVJ.

'Set was so excited he tried to have sex with the vehicle.

Bardi turned 29 last night, and Offset wanted to outdo her gift.

So her bought her a mansion in the Dominican Republic, Cardi's family's homeland.

The Migo played a video of the new abode during Cardi's birthday party.  It looks like it has a pool on the roof.

A Lamborghini Aventador goes for about 600K.  We're not so sure about real estate in DR, but even if 'Set paid less than that for Bardi's gift, a vacation home is a bigger gift than a car.
