Kourtney Kardashian celebrated her 34th birthday with a big bowling bash in L.A. on Wednesday, April 17. The birthday girl was joined by mom Kris Jenner, brother Rob, and sisters Kim, Khloe, Kendall and Kylie.

Curiously missing from the shindig was Scott Disick, Kourt’s boyfriend and baby daddy. Also apparently not there were their children Mason and Penelope or Kourt’s step dad Bruce Jenner.

Sister Kim Kardahian who was dressed in casual chic for the occasion in distressed boyfriend-style jeans and a tight black T-shirt and jacket congratulated her sis on Twitter: “Happy birthday to my big sister and mentor. I love you so much!”
