Seeing the gorgeous display on their screens, fans headed straight to the comment section.

One person wrote: “Lovely people,” followed by love heart emojis.

Another shared: “Yᴀsss!!!! Love the new pics.”

Meanwhile a third commented: “Love how she posting a selfie for her sis’s birthday… main character energy.”

The business mogul put on a stunning display

Despite the pair handling their low-key split with grace and away from media attention, Kim was reportedly furious after her ex-husband Kanye West posted a meme with a fake New York Times front page on his social media platform with a headline that read “Skete Davidson ᴅᴇᴀᴅ At Age 28”.

Discussing the matter further, a source told DailyMail.com: “Kim won’t stand for this. She is demanding that Kanye take the post down, but he won’t.

“She has been vigorously defending Pete. She’ll never get back together with Kanye over the way he’s treated the people she loves and respects.

“She has tried incredibly hard to have a good co-parenting situation for the children. She won’t stand for this type of behaviour from him.”
