Kim Kardashian's relationship with Kanye West has already lasted longer than her marriage to Kris Humphries, and now sources are saying she's pushing Yeezy to pop the question for her birthday. This will end well.

The Daily Mail reports that Ryan Seacrest, one of the producers of 'Keeping Up With the Kardashians,' hinted a possible engagement on his radio show. When asked about rumors of K.K. demanding an engagement ring for her 32nd birthday (tomorrow, Oct. 21), he murmured, "I think we could definitely see an update on this story on Monday."

Radar Online reports that Ye is indeed planning to propose -- he's just looking for the perfect ring. "It’s only a matter of time before Kanye pops the question," a source revealed 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."

While it was reported that West was spending big bucks on a huge birthday party for his princess, the couple are actually traipsing around Rome together to celebrate the big 3-2 for the reality starlet. Here's hoping they have enough fun to distract from West's leaked sex tape with a Kim K. doppelganger ... and the fact that Kim's still legally married to Humphries.
