Did Kanye put a ring on it?

Kim Kardashian showed off some major bling -- and major curves -- while shoe-shopping Wednesday at a Christian Louboutin store in Miami.

Strutting around the city's posh Design District, the reality star, 32, turned heads in a sleeveless black leather peplum top, silver stiletto pumps, and super-snug gray skinny jeans that emphasized her world-famous derriere. She also toted a pricey (five figures!) black crocodile Hermes Birkin bag.

But the purse wasn't even the buxom brunette's most outrageous accessory. That honor went to the giant, oval-shaped diamond ring on Kardashian's pinky finger.

Engagement rumors about the E! Network beauty and her rapper beau Kanye West, 35, have been rampant in recent weeks. Kardashian herself told the women on the View that she "believes" she'll marry the hip hop star, whom she started dating just seven months ago. And last week, Keeping Up With the Kardashians producer Ryan Seacrest said on his KIIS-FM radio show that he thought West would pop the question on the couple's romantic trip to Italy to celebrate Kardashian's 32nd birthday, which was Sunday, Oct. 21.

In any case, the PDA-loving pair appear to be in it for the long haul.

"[Kanye has] been there through so many different stages of my life and before I was famous, so this relationship is a different thing entirely," Kardashian told Tatler earlier this month. "I can't even think about being with anyone else than the man I'm with."
