Things keep getting more and more serious between Kim Kardashian and Kanye West.

After dating for months and spending nearly every day possible with one another, the couple is reportedly shopping for real estate together.

Kardashian and West recently spent time in England while Kardashian was promoting the newest extension of her clothing line, Kardashian Kollection for Dorothy Perkins, which she designs along with her sisters Kourtney Kardashian and Khloe Kardashian. The trip went so well that the couple has decided to shop for homes in the London area.

"[Kim and Kanye] are just fascinated with British culture. They so welcome in England and now feel ready for a change ... and a new challenge outside of the U.S," a source said. "Kim K. especially loves the idea of a cute, nice three bedroom townhouse located close to one of London's beautiful family parks."

And a new home may not be the only thing the couple is planning. An insider close to Kardashian and West told Radar Online that the 35-year-old rapper has been planning to pop the question for quite a while, and he is simply waiting for the right time and the perfect ring.

"It's only a matter of time before Kanye pops the question," the source said. "They are madly in love with one another, and as far as Kanye is concerned he wants to spend the rest of his life with Kim. It's just a case of making sure the ring is perfect because she's his princess."

Kardashian recently discussed what her nuptials would be like when she decides to marry for a third time during an interview with Tatler magazine. She said the ceremony would be completely different than the one she had with Kris Humphires, which was televised on her show "Keeping Up With The Kardashians."

"It had always been my dream to have a big wedding, and when people said that I'd made it over the top for the show, that was just me: I am over the top. But the next time, I want to do it on an island with just my friends and family and that's it," she said.
