The 36-year-old reality star took her three-year-old daughter - who she has with her husband Kanye West - to the Forum in Inglewood, California, on Friday (31.03.17) to see the 'Dangerous Woman' hitmaker in action, and was got the VIP treatment when they headed back stage to meet the star.
The 'Keeping Up with the Kardashians' star posted a photo on her Instagram account of Ariana, 23, playfully sticking her tongue out as she cuddles little North, with Kim stood behind them.
Kim simply captioned the snap with a heart emoji and tagged Ariana's Instagram account.
And the brunette beauty also took to Snapchat to share a series of videos from the concert including one clip of North - who was wearing cat ears in homage to one of Ariana's signature looks - singing along to the star's hit single 'One Last Time'.
An onlooker told E! News: ''North looked so excited in her cat ears. The pair went to their seats a few songs into the show to avoid being recognised.''
According to the publication, stars including Niall Horan, Camila Cabello, Drubel, and Ramona Singer were also at the concert.
Meanwhile Kim - who also has 15-month-old son Saint with her spouse - recently underwent surgery on her uterus as she's desperate to expand her family and have a third child.
She said: ''I have to go in and repair my uterus because I decided I'm going to try to have one more baby. Isn't that exciting?
''I have to have a surgery on my uterus to kind of repair this hole, so they need to like clean that out and then there's scar tissue. It will still be a really high-risk pregnancy, just you'd be able to get pregnant.
''Having more kids is definitely going to be a struggle. I've gone through so much with really bad deliveries that the doctors don't feel like it's safe for me to conceive again myself. This surgery is really the one last thing I can try.''
