Kanye West has been mocked online for referring to his wife Bianca Censori as ‘stepmother to our children’ in a bizarre birthday tribute. 

The controversial American rapper, 46, took to Instagram to mark Bianca’s 28th birthday on Friday by sharing a photo of the brunette staring into the camera, along with a heartfelt caption.

‘Happy birthday to the most beautiful super bad iconic muse. Inspirational, talented artist, loving by my side everyday when half the world turned their backs,’ he began.

West then praised Bianca for being an ‘amazing stepmother’, and referred to the four kids he shares with ex-wife Kim Kardashian as ‘our children’.

‘The most amazing stepmother to our children. I love you so much, thank you for sharing your life with me.’

Many of his followers couldn’t resist roasting Kanye for the turn of phrase, with some speculating that he was taking a dig at Kim.

‘Our kids? Is he confused? [laughing/crying emoji]l,’ one user commented.

‘Our children? You mean ‘Your children?’ SMH,’ another asked, while someone else added: ‘Imagine Kim posted ‘Our children’ with another guy though.’

Kanye shares children North, 10, Saint, 8, Chicago, 5, and Psalm, 4, with his ex-wife Kim.

Melbourne-born Bianca Censori has undergone quite the transformation since her wedding to Kanye West one year ago.

A far cry from her days as a little-known Melbourne architect, Bianca made global headlines on Tuesday after Kanye shared a trio of raunchy photos of her posing in barely any clothing on Instagram.

Kanye shared the images as he prepared to drop his new song with Travis Scott on Tuesday, ahead of the release of his new album, Vultures, which is expected later this month.

In the images, Bianca was seen posing around the couple’s home wearing an  extremely revealing bra, G-string, leather corset, stockings and a fur stole that barely covered her modesty.

Bianca and Kanye secretly wed in a non-legally recognised ceremony in December 2022, just one month after he finalised his divorce from Kim.

In September, friends expressed grave concerns that he was manipulating Bianca into a ‘radicalised’ version of Kim, who he often referred to her as his ‘muse.’ He also heavily influenced her fashion choices.

‘Kanye is trying to make Bianca into a radicalised version of Kim – almost like Kim 2.0,’ a source said at the time.

‘The difference is that when Kim was with Kanye he was respected in the fashion world. He has since lost this respect.’
