Kim Kardashian West attended her high school reunion on Friday (13.04.18)

And Kim - who has children North, four, Saint, two, and three-month-old Chicago with husband Kanye West - was looking forward to the occasion as she knew there was no chance of any awkward run-ins with her former classmates.

She said in a clip posted on her Instagram Story: "So my friends are worried that we’re gonna run into people that they were mean to and I feel so good about my conscience that I was so nice to everyone."

At the reunion, the 'Keeping Up With the Kardashians' star showed off her year books and posed for photos with her classmates, and though she was having a good time, she admitted it felt "crazy" to be back at school.

She said in another clip: “We are walking down the same halls that we walked 20 years ago, this is crazy!”

Meanwhile, Kim has thanked her personal trainer, Melissa Alcantara, for helping transform her body.

She showed off a bikini picture from her recent vacation to Turks and Caicos and wrote on Instagram: Shout out to my trainer @fitgurlmel who really changed my body. When I wasn’t happy with what I saw back in the mirror I spent a whole year training so hard 5 or 6 days a week putting in a lot of work and changed the way that I eat and there’s such a noticeable difference. I am firm and less cellulite and so much more confident. SO THANK YOU for waking up at 5am to do crazy body building workouts & sprints that I hate & putting me on to this lifestyle (sic)"
