This is family business.

Looks like things are getting more serious between Kanye West and his new “wife,” Bianca Censori, as the architect was spotted holding hands with Ye’s eldest daughter at his 46th birthday bash in Los Angeles over the weekend.

In photos obtained by Page Six, Censori and North were all smiles, holding hands as they made their way into the private party together Saturday night.

North – whom West shares with ex-wife Kim Kardashian – wore a gray sweater with shorts and black boots. The 9-year-old also had visible red markings on her face, but it is unclear if they were from an injury or merely face paint.

Meanwhile, Censori sported her usual gelled-up pixie cut, sporting a black leather trench coat with matching heeled boots, while West kept it casual in an all-black ensemble.

Inside the bash, the trio seemed to be getting along swimmingly.

A videographer at the party posted a video of North filming her father lip-syncing his song “Off The Grid” while Censori grinned in the background.

In another video, nearly-nude models lay atop tables as sushi was served on trays covering their breasts and vaginas.

The private party, which had stars such as Chloe Bailey and Ty Dolla Sign in attendance, featured a minimalist, candlelit aesthetic.

As previously reported, North and Censori have been on multiple group outings ever since the architect married the “All Falls Down” rapper in a non-legally binding ceremony in January.

The trio met for dinner at Nobu in Malibu, Calif., just weeks after the nuptials, and were spotted out at Universal Studios Hollywood together in March. That same month, the three went to church together.

As for North’s mom — who also shares Saint, 7, Chicago, 5, and Psalm, 4, with West — Kardashian said that co-parenting with West is “really hard.”

“I had the best dad, and I had the best memories and the greatest experience and that’s all I want for my kids as long as they can have that,” Kardashian shared in a 2022 interview.

The two finalized their divorce in November 2022 after eight years of marriage.

The reality star, 42, added that she has worked to shield her children from the barrage of controversial comments their father has made, including a slew of anti-Semitic remarks the rapper shared in October 2022.

“If they don’t know the things that are being said or what’s happening in the world, why would I ever bring that energy to them? That’s really heavy grown-up s–t that they’re not ready to deal with.” 

While Kardashian has kept mum in the past few months when it comes to West’s latest romantic venture, a source told Page Six in January that she was not quite ready to accept the Yeezy employee as part of the family.

“She hates her,” the insider alleged. “She’s pretty. And Kim hates pretty girls.”
