Kim Kardashian Engaged? Star Wears Enormous Diamond Ring [PHOTOS]

Fueling further speculation that she is engaged to boyfriend Kanye West, Kim Kardashian was spotted wearing an enormous diamond ring as she hit the streets of Miami on Wednesday.

The reality star wore the huge ring along with a leather blouse and grey jeans as she made her way around Miami while filming the latest season of her show, "Kim and Kourtney Take Miami," with her oldest sister Kourtney Kardashian.

Despite Kim's new bling, sources close to the couple say they are still not engaged. But that doesn't mean it hasn't been a possibility for weeks.

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."

The speculation hit a fever pitch last weekend when West whisked Kardashian away to Rome to celebrate her 32nd birthday, and Ryan Seacrest added fuel to the fire on his KIIS FM radio show.

Seacrest - who is an executive producer on "Keeping Up With The Kardashians" - was reporting on a story that Kardashian demanded an engagement ring for her birthday, and he told his co-host Ellen K that he expects more news could develop on the story by the next Monday, the day after Kardashian's birthday.

"I think we could definitely see an update on this story on Monday," Seacrest said.

Seacrest's words are being carefully analyzed because of his close relationship with the Kardashian clan from a business and production standpoint.

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.
