What do you get for the rap star who has everything? Shopping for Kanye West can’t be easy, but Kim Kardashian proved that money ain’t a thing today after she copped Yeezy a super rare Lamborghini Aventador LP 700-4 for his 35th birthday. Lamborghini mercy indeed-- the whip goes for $750,000.

Hopefully TMZ didn't ruin the surprise when they published pics of the rare black two-door sports car. According to the site, Kardashian couldn't bring the gift to 'Ye because he's in Ireland with Jay-Z for another stop on the European leg of their Watch the Throne Tour, so Kim took a video of the car in L.A. so she could show him.

"Kimye" began dating earlier this spring and have since become prime targets for the paparazzi, who have snapped the lovebirds on both coasts. The pair were also spotted at the Cannes Film Festival in May, where Yeezy premiered his "Cruel Summer" film. Last week, TMZ reported that both Kanye and Kim put their Los Angeles-area homes up for sale, fueling rumors that the two are planning to move in together.

On Wednesday, 'Ye and his G.O.O.D. Music comrades dropped the video for their "Mercy" single, which they spot in an art-deco inspired parking garage. Now that the Louis Vuitton Don has a new toy to rap about, we wonder if a remix is on the horizon.
