Kourtney Kardashian is celebrating her 34th birthday today (happy birthday, Kourt!), but the family got together last night to honor the birthday girl at a bowling party. Kim kept it comfortable in a pair of classic ripped jeans and a black t-shirt, and posted a ton of photos from the party on her Instagram account. The mother-to-be shared this cute picture of the family with the caption, "Fam bam."
