After jetting back from the Hamptons without longtime partner Scott Disick on Friday, Kourtney Kardashian has been quite busy! But the oftentimes grumpy reality TV star was in great mood when X17 photographers snapped her picture on Saturday, so it appears as though none of the family drama is bothering her...

Kourt and her assistant stepped out to grab some food in Malibu, and later in the day she let sister Kim use her backyard to throw a crazy Coachella-themed birthday bash for daughter Nori, who turned one last weekend.

Back back to Kourt and Scott! After the news broke that they were expecting their third child together, she flew back to Los Angeles, leaving her hubby all by himself at the $14 million Hamptons rental home where they're shooting their spin-off reality show.

Kourt has reportedly had it with Scott's partying and childish antics, and during a heated squabble, a source tells Us Weekly, "Kourtney was yelling at Scott after she found an inappropriate picture of him with another girl." She reportedly screamed during the argument, "You need to be a more responsible father and get better. There is another baby on the way! You need to straighten up or get out!"

Apparently she kicked him out of the pad after their fight, but it looks like something changed, because he's currently there living it up with his bros, and he even enjoyed a nice relaxing day on the water!

Hmm, so when are these two going to be reunited? Or is this all just a made-up plot line?
