Pregnant Kim Kardashian hit the gym to keep her growing body in check, but BEFORE she sweated it out, the 32-year-old reality star visited Cartier in Beverly Hills.

Sounds like someone may be picking out some engagement bling! Nothing but the best for Kanye West's baby mama.

The high-end jewelry store confirms that Kim K had her beautiful eyes set on the Cartier d'Amour solitaire surrounded by diamonds.

Could Kim And Kanye be walking down the aisle sooner rather than later?
