Kim and Kanye with Kourtney's son Mason.

Rumors and suggestions Kim Kardashian is pregnant have been increasing with her recent weight gain and now a report has claimed the reality TV actress is desperate to get married to boyfriend Kanye West.

Is she pregnant and engaged?

She may have a big rock at the end of the weekend, according to American idol host Ryan Seacrest, though he didn't mention any possible baby bump just yet.

The 'Keeping Up With The Kardashians' producer has hinted Kim might be getting more than she bargained for when Kanye whisked her off to Rome on a romantic break with the intent of celebrating her 32nd birthday tomorrow.

Discussing whether there is any truth to the rumours that Kim is "demanding an engagement ring" on his KIIS radio show, Ryan told his co-host Ellen K: "I think we could definitely see an update on this story on Monday."

Twice-engaged Kim - who is still in the process of divorcing Kris Humphries - has made no secret of wanting to settle down and start a family, and recently confessed she had finally found her match in Kanye.

The 35-year-old rapper is said to have been searching for the perfect ring to bestow on his "princess" and make their commitment official.

A source told Radar Online: "It's only a matter of time before Kanye pops the question. 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."

The website adds that "no one could be better placed" to know about the proposal since Ryan works very closely with the Kardashian clan on their E! reality show.
