Kim kardashian poses for a picture as Redbook celebrates first ever family issue with the Kardashians held at The Sunset Tower Hotel on April 11, 2011 in West Hollywood, California. 
Kim Kardashian Kim is the oldest sister of the Kardashian klan, and she's taking her family seniority seriously. While sister Kourtney Kardashian got some serious birthday clubbing on in Vegas this weekend, infamous light drinker Kim stayed home and watched Kourtney's little tyke Mason. Not to knock down her Saturday night company. According to Kourtney via Twitter, Kim and Mason "slept in bed together and had a slumber party" for their first night alone together.
As for Kourtney and player/boyfriend Scott Disick? They celebrated her big 3-2 at the grand opening of Gallery Nightclub in Planet Hollywood. (She tweeted: "The club was amazing!!")
It's just really good to know Scott wasn't starting fist fights while smoking cigars or flirting with other ladies in his three-piece suit (yes, he's done all of the above.) Kourtney danced with friends, sipped champagne, and was presented with a cake adorned with feather-flashing dancers. We don't get it either, but maybe Kim didn't miss out after all!
