Kim Kardashian sports her new 15 carat engagement ring here after her man Kanye West proposed Monday at AT&T Park in San Francisco. It happened in front of friends and family while a 50 piece orchestra played music by Lana Del Rey. The couple already has a baby named North. Let's see if Kim's thrid marraige lasts longer than her second attempt when she lasted 72 days through wedded bliss with NBA player Kris Humphries in 2011. By the way, he sold her engagement ring from that fiasco last week for $749,000. A lot of bling has graced her finger! Wouldn't you be nervous walking around town with such a target on your left finger?
