Keeping herself busy, Kourtney Kardashian was seen returning to her hotel in New York City last night.

Carrying her adorable son Mason, the “Keeping Up with the Kardashians” starlet looked a bit tired from filming her reality show in the big city and doing promotion for her new Kardashian Kollection.

Speaking of which, Kourtney recently chatted with press about what it was like to work with her sisters Kim and Khloe on the new line.

“The most challenging part was trying to incorporate all our individual styles in the Kollection — but as time went on, it became a very natural process. When we all loved a certain print or fabric, we knew it had to be included. For instance, we are all obsessed with animal prints and bold, graphic patterns.”

When asked which sister’s closet she’d like to raid, Kourtney confessed, “Kim and Khloe both have the most insane accessories! Shoes, bags, jewelry, belts — they’ve got it all! It depends on their moods, but Khloe would probably share more. So I’d go for Khloe’s closet!”
