The brunette beauty, 29, and the rapper, 46, treated North, 10, Saint, eight, Chicago, five and Psalm, four, to a fun-filled night out at the movies after they dined at celeb hotspot Nobu in Malibu.
The model — who was pictured with Kim for the first time at Kanye's album party — slipped her famous figure into a silver catsuit as she strutted ahead of the family towards the theater.
In a bid to keep a low profile, Kanye donned a dark jacket, matching pants and sunglasses as he held the hand of his adorable son, Saint, with the other three kids following closely behind.
The outing comes just hours after Kim, 43, accompanied the four children to her mom Kris Jenner's holiday shindig, where they reunited with the rest of the Kardashian/Jenner clan.
Details of the festivities were detailed by Kim on her social media account, as she gave a peek at Kris' decorations including the tablescape, which had egg plates and napkins as well as a pastel, floral tablecloth.
The makeup mogul, was married to Kanye from from 2014 to 2022, also shared a picture of an Easter egg that was decorated from her son Saint that had 'Mom' written in pink marker.
And on their joint TikTok caption, Kim and North shared snaps from the party and wrote: 'Happy Easter Jesus loves you.'
The holiday festivities come after Bianca and Kim shocked fans by being spotted together for the first time at Kanye's Vultures Listening Party just two weeks ago.
In a clip from the event, Bianca can be seen in a pink top as she films the performance on her phone with Kim stood next to her.
Also in attendance were Chicago and Psalm.
Kim is said to have an amicable relationship with Bianca – but is reportedly not a fan of her parading her risqué fashion in front of her children.
‘Kim instructed Kanye to never let Bianca dress like that around their kids,’ a source told DailyMail.com exclusively. ‘She is truly surprised that Kanye would let his wife leave the house like that.’
Australian-born Bianca has been pictured in a slew of headline-grabbing outfits since she married Kanye in December 2022 – less than one month after his divorce from Kim was finalized.
Insiders have told Daily Mail that Censori wants to step away from the spotlight, saying, 'She needs a break and needs to step back.'
'She feels like he is using her as a free marketing tool – as does everyone else,' the source alleged.
'These past couple of months have been an experience, but she really wants to focus on having children after the album drops. She knows she is overexposed.'
Kanye recently appeared to defend his wife's bizarre, and at times obscene outfit choices, as well as his decision to post half naked photos of her on his Instagram.
‘Ima post my wife as much as I want bro,’ he told his 19.5 million followers on Tuesday. ‘It makes me happy. Some people don’t want you to be happy. They want you to make them happy. I decided to make myself happy and I’m happy with that [sic].’
Unlike Bianca's raunchy wardrobe, Kim was asked to change her outfits if Kanye felt she was showing too much skin, with the artist heavily influencing her fashion choices during their seven-year marriage.
'Kanye did the same thing he is doing with Bianca to Kim throughout their marriage,' the source continued. ‘The difference is that when Kanye dressed Kim, he was respected as a person – as an artist.
