Kim and Kanye have spent $4 million since they started dating in April

The couple have only been flaunting their KimYe since April, but already they've spent a hefty $4 million together.

Life & Style reports the duo have spent $700,000 on first-class airfares with trips to LA, New York, London, Paris and Mexico.

While holidaying in the South of France, the lovebirds cruised around town in a $1 million Mercedes and a $230,000 Ferrari before taking to the seas in style on a $250,000-per week yacht.

Then there's the $750,000 Lamborghini Kanye bought for Kim's birthday. Oh, and prime seats at a Lakers game for $2700 a head.

The obligatory chocolates, champagne and pretty flowers would hardly make a dent.

Rapper-turned-designer Kanye is also willing to spend up big to cover his girlfriend's impressive caboose, reportedly blowing $500,000 on clothes for Kim on a recent trip to Paris.

Speaking of threads, Kim tweeted a pic of herself (see below) wearing an interesting pair of Kanye-designed, UGG boot-turned-stilettos a couple of days ago, prompting fears he is ruining her good fashion sense.

Meanwhile, the couple have taken their relationship to the next level, filming a commercial for the 2012 MTV VMA Awards with host comedian Kevin Hart.
