A week after her sister Kim Kardashian joined Snapchat, Kourtney Kardashian made the plunge and decided to start an account of her own, and we've never felt so blessed.

North "Nori" West has become the undisputed star of Kim's hilarious story, and we now know that Kourtney and ex Scott Disick are totally fine -- they hang out all the time!

Rob Kardashian celebrated his birthday this week, and Kylie, Kendall and Khloe brought the LOLs by going incognito on a Hollywood bus tour. But enough of the Kardashian-Jenners.

Serena Williams also showed off her bangin' bod in a series of sexy swimsuit selfies during the Indian Wells tennis tournament in Palm Springs. Reese Witherspoon and Jessica Alba hung out with their look-alike children, while Taylor Swift made a few surprise appearances of her own.
