Kim Kardashian had lately been posting several pictures of herself in a bikini, on social media.
Kim documented the night on Snapchat, showing her millions of followers around her old school.
Kardashian, who wore a plunging white outfit, later posed with her high school besties.
The 37-year-old has had one huge weekend.
The mum-of-three wrote in the caption: 'I deleted some vacation pics because I didn't like the vibe on my page but I re-filtered them and reposting some!
First Alert Forecast: Cold start for Sunday
Cool temperatures in the beginning of the week will give way to a warming trend midweek through the end of the work week. The winds will start ramping up Sunday morning, and it will be warm and very humid.
Friday morning, Kim tweeted that the baby is "so lovely", adding that Khloe is "so strong" and that she made childbirth "look... easy".
The Daily Mail noted that Kim's Instagram followers were harsh in their comments about Kardashian seemingly ignoring Khloe's drama as she posted bikini photos.
Glad Kim K had a good time looking back, though!
"Kim and Kourtney Kardashian are furious with Khloe's boyfriend Tristan Thompson - but played nice while with him in the star's birthing suite".
The Keeping Up with the Kardashians family is known for having outspoken views.
"I feel so good about my conscience that I was so nice to everyone", said Kim, proud of her accomplishments.
