It also has something to do with Kourtney launching the Kardashian Kollection at Dorothy Perkins, but what we're most interested in are the adorable vacay pics she's been posting.
Behold, the family taking in the city from the London Eye! "The London Eye really had such spectacular views of the city, especially at night time!" Kourtney blogged.
We're sure little Mason Disick loved seeing the city, but toy shopping probably ranked higher on his list.
"Scott and I took Mason to Hamley's which is supposedly one of the largest toy stores in the world!" Kourtney posted. "We had so much fun looking at all the cool toys and picking some toys to bring home with us."
The trip across the pond also included bonding time with the rest of the Kardashian gals, including a dinner date night with Kimye and Khloé Kardashian Odom!
"Scott and I met up with Kim and Kanye for a double date at Hakkasan in London," a blog from Kourtney said. "Khloé came straight from the airport to meet us because I missed her so much that I needed to see her face and give her a hug!"
Well, after seeing these photos we're missing the Kardashians a whole lot! Which is why we can't wait for the all new season of Kourtney & Kim Take Miami coming to E! this January.
