AceShowbiz - Kanye West's wife Bensori Censori opted for her go-to racy style for her special day. The Yeezy architectural designer almost spilled out of her skimpy bikini top while celebrating her 29th birthday in Las Vegas on Saturday, January 6.

A video obtained by TMZ featured the Australian native and her rapper husband walking hand-in-hand through the Wynn resort. The architect rocked a super tiny black top that did almost nothing to cover her breasts. For the occasion, she paired the risque look with a thin white skirt.

Bianca also opted out shoes for the occasion. It should be noted that while Wynn's dress code prohibits flip flops and tennis shoes, it mentions nothing about going barefoot. It also asks guests to dress appropriately and prohibits bathing suits. As for Ye, the 46-year-old controversial star wore jeans and a dark gray, long-sleeve shirt.

Another video, meanwhile, saw Bianca being in high spirits during the celebration. While sporting a huge smile on her face, she could be seen blowing out candles after her friends sang "Happy Birthday" to her.

Throwing the party wasn't the only Ye did for Bianca on her birthday. On the same day, the former husband of Kim Kardashian took to his Instagram account to pen a sweet birthday shout-out for Bianca.

"Happy birthday to the most beautiful super bad fun iconic muse inspirational talented artist masters degree in architecture 140 IQ," so he wrote alongside a close-up picture of Bianca. The Chicago star then thanked her for "loving by my side everyday when half the world turned their backs on me."

The "Vultures" rapper additionally hailed Bianca as "the most amazing step mom to our children," referring to her four children North, Saint, Chicago and Psalm whom he shares with the SKIMS founder. Concluding his message, he wrote, "I love you so much thank you for sharing your life with me."
