Kourtney Kardashian Launching New App But Will She Miss Kourtney's Birthday Celebrations?

Kourtney Kardashian turns 36 on Saturday (18th April) and her family have wished her a Happy Birthday on social media. They are throwing a party at one of the family's favourite clubs, 1OAK in Las Vegas, but one of her siblings may not be able to attend. Khloe will reportedly be absent from the occasion as she is launching a group messaging app, Regroupd.

30-year-old Khloe is in Coachella where she will be entertaining more than a hundred celebrity guests and providing them with tutorials on how the new app works. According to reports in TMZ, Khloe, who is fronting the app, has rented out a huge house in the desert for the occasion. Guests will be able to relax by the pool and enjoy burgers and ice cream from two of the food vans on standby. Kendall and Kylie Jenner have also joined her, according to Tweets on Regroupd's feed. So it is possible the sisters will fly out to Las Vegas in time for the party later on.

The entire family have wished Kourtney Happy Birthday on Instagram with Khloe posting a lengthy caption along with a picture montage of the two together but included a message to all her sisters. "My life would be meaningless without ALL of you," Khloe wrote. "So with every single birthday I am more and more appreciative that we get to spend another year together only strengthening our bond as soulmates every single one of us."

Kourtney's mother, Kris Jenner, also posted a photograph on Instagram. The picture was of Kris holding Kourtney as a baby and Kris described herself as "obsessed" with her eldest daughter from "the moment you were born".

"When you were born I realized what true love really is," Kris added. "You are the most amazing Mom I have ever known, the best daughter, friend, sister, and partner and you are loyal to a fault... You are the most beautiful person inside and out and I am so blessed and honoured to be your Mom and we are all better because we get to share life with you."
