Kardashian Sisters Show Off Their Racks at Charity Poker Tourney

Kim, Khloé and Kendall went all-in for a great cause over the weekend.

The reality star sisters, and Kris Jenner, were guests at the "If Only" Texas Hold'Em charity poker tournament held in Inglewood at The Forum. The benefit raised money for the City of Hope, a world-class cancer treatment and research center.

The winner of the tourney got front-row tickets to an upcoming Eagles concert at The Forum, along with backstage passes. Other prizes included Fleetwood Mac tickets, and a chance to sparkle like the Kardashians with a Lorraine Schwartz diamond bracelet worth $17,000 .

During the event, the girls couldn't get over how skinny Kim has gotten.
