Later, Scott exclaims, 'Look how beautiful it is out! It is everything and more.'

Kourtney reflects upon Scott's past behaviour, saying, 'In the past, Scott has always been such a Debbie Downer on most of our family vacations.

'I think it's great that he has been working on himself. I definitely notice a difference in his attitude and I'm hoping that this is a change that will continue.'

As Kourtney speaks, a series of flashbacks play, showing Scott complaining and whining during past family outings.

Start stompin' in your Airforce 1's like Kourtney

Her daughter might look like a sweet and little ballerina but Kourtney Kardashian looks like she has some serious street 'kred' with that shoe game!

The mom of three carried her precious gift in one hand and her child in the other while in Los Angeles. She rocked a sporty attire and looked 'flyaa then evaa' with her black zipper jacket, black tights and cool sneakers.

Kourtney wore the Nike Airforce 1 Ultra Force Mid BHM, the sneakers retail for $360 but you can get them for $184 at August May Styling.

The sneakers have cool black and white detailing that are similar to patchwork. You can never go wrong with Airforce 1's on your feet! Wear em' out while running errands or wear them with leather jeans, a fitted black v-neck and a leather jacket...it would be like rocker chic meets Kanye.

Check out our style deck for different shoe game options if your not into the sneaker print.
