“Kim Kardashian’s daughter North West and Jessica Simpson’s daughter Maxwell Drew Johnson were revealed to be best friends on Monday.

The pairing came to light when Kim, 43, was photographed in New York for North’s 11th birthday with Maxwell, 12, and Selena Gomez’s half-sister, Gracie Elliot Teefey, 11. The girls appeared to be wearing matching pale pink T-shirts that read I Heart NW as they left a luxury hotel together. Olympia, six, and Sienna, seven, are best friends and together enjoy regular play dates and trips abroad to sunny places like Cannes. While Olympia’s mother is a former American professional tennis player – and widely considered one of the greatest tennis players of all time, Sienna’s mother is a crank music-loving singer-songwriter who burst onto the scene with her debut studio album, Goodies in 2004.

Their mothers’ friendship blossomed when they were still in their 20s, as they shared their party lifestyle with family, and attended baby showers when they were pregnant. Speaking about their friendship, the mothers said: “I think the key to our friendship is the fact that when we come together, it’s not about what we do in our careers, it’s about experiencing our true selves with each other.” One is the daughter of a rock star, and the other is the son of a Hollywood actor who starred in famous films such as The Holiday and Sherlock Holmes.

While speaking about being part of the Primrose Hill 2.0 set for Tatler in 2018, Anais opened up about her friendship with Rafferty. “We all still live there, we grew up together and are relatively close,” she explained, noting that Rafferty is a friend but a bit older, while his sister Iris is younger. If there was ever a perfect pairing, this would be it, and it’s no surprise considering their mothers enjoyed similar career paths in the entertainment industry while flirting with equally controversial headlines.

In fact, one of them enjoyed a pop music career that nearly went nuclear before establishing herself as a regular reality TV and unlikely ambassador for OnlyFans. The other shrugged off her iconic modeling vanity to become a Loose TV presenter and reality TV star in her own right. Although it is doubtful that any of these children slept in the Australian bush, their mothers certainly did. During their falling out, both women experienced a lot of drama and grief before they were finally able to bury the hatchet, thanks in part to the bond between their children. Heidi’s mother enjoyed a pop music career that nearly went nuclear before establishing herself as a regular reality TV and unlikely OnlyFans ambassador.

Meanwhile, Princess’s mother has ditched her modeling persona to become a free-spirited TV presenter and reality star in her own right. Some might say it’s a match made in music heaven – and they’re not wrong. While Gene, 22, is a musician in his own right, his father became a household name as one of the founding fathers of Britpop in the mid-1990s. Meanwhile, Sonny, 22, is linked to rock royalty thanks to his grandfather, who helped define pop music as we know it after he rose to fame in the 1960s.

Both influential figures in the music industry, Gene’s hard-to-please father credits Sonny’s grandfather and his legendary bandmates as his biggest inspiration. In fact, Jen’s father admitted he “freaked out” after meeting his hero backstage at a party. “His voice and everything, it sounded like I was tripping,” he told Far Out. Even his name… was just amazing.”
