All the women stepping out for a public affair birthday bash!

Jessica Simpsons eldest daughter Maxwell—who turned 10 on May 1—celebrated in fashion with a birthday celebration alongside a few of her closest associates and household. As shared on the “Public Affair” singer’s Instagram Stories on May 4, Kim Kardashian‘s daughter North West, 8, and Kourtney Kardashian‘s daughter, Penelope Disick, 9, have been among the many celebratory partygoers.

In case you missed it: In early April, Jessica shared the story behind Maxwell and North becoming BFFs. The two met while taking part in basketball on a crew that was coached by her husband Eric Johnson, and their friendship grew as a result of they living shut to one another.

“One of Maxwell’s best friends is North,” she informed Us Weekly. “And so, watching North, she is amazing, she is a great kid, and she will be a part of the change in this world. She and Maxwell alone.”

In a birthday shoutout to her now 10-12 months-previous, Jessica—who can also be a mother to Ace, 8, and Birdie, 3—expanded on her sentiment about Maxwell’s shiny future.
