Kim Kardashian and Kanye West: Expensive romance!

OHMYGOSSIP — Kim Kardashian‘s romance with Kanye West is costing the couple a pretty penny! According to America’s Life & Style magazine, the pair have spent a cool $4 million on their relationship since debuting as a couple in April.

They pair have spent roughly $700,000 on first-class airline seats and private jets. They regularly take in a LA Lakers game courtside at the Staples Center, where prime seats go for $2,700 apiece.

When they were in Cannes, France, the pair traveled around in a $1 million Mercedes-Benz and a $229,825 Ferrari. Back home in LA, Kim even gave Kanye a $750,000 Lamborghini as a birthday present.

The pair spent $250,000 to rent a $38 million yacht, christened Lady Joy, for a week-long cruise.

Kanye scooped up $50,000 worth of designer threads in Paris for the Prada- and Givenchy-loving reality star.

Meanwhile, Kim has been rapidly shedding the pounds — and her friends and family are adamant it’s down to the fact she enjoyed a lot of intimate time with her rapper boyfriend.

“We jokingly refer to it as the sex diet. When one of us is having regular sex, that tends to’ burn calories and kill the appetite. Losing seven pounds in seven days means being a very naughty girl,” a source said.

“Kanye loves her curves and has told her repeatedly that she shouldn’t get too skinny. He’s always encouraging her just to be happy and healthy and do things for herself and not give in to peer pressure, which is why he doesn’t think she should lose weight.

“Kim was speechless, especially when he told her he missed her love handles. Kanye can’t understand why she has lost weight when she knows it’s not the look he likes. He thinks Kim should be doing everything to please him — not herself.”
