For their public outing, the reality star looked ready for a night out on the town, wearing a hot pink mini dress with a cutout highlighting her rock-hard abs. Adding in a bit of comfort to the look, she accessorized with a pair of Yeezy sneakers. The rapper, who announced on Saturday that he had changed his name to YE, was dressed casually in a beige sweatshirt, white pants and sand-colored Yeezy footwear. Kim Kardashian Didn’t Know If She and Kanye West Would Last When She Got Pregnant with North The insider told PEOPLE that the musician’s decision to go by a new moniker “must be something very recent.” “It could be one of Kanye’s spontaneous ideas that he sometimes wakes up with in the morning. Usually, Kim will just roll her eyes at these ideas and ignore,” the insider adds.

I am YE,” he wrote. The name has a lot of symbolism for the musician, who titled his last album YE. In addition to being a shortened version of his full name, the moniker also holds a deeper, spiritual meaning. “I believe YE is the most commonly used word in the Bible,” he told Real 92.3’s Big Boy when promoting his music in June. “In the Bible it means ‘you.’ So I’m you, I’m us. It went from being Kanye, which means the only one, to being just YE — just being a reflection of our good, our bad, our confused, everything. I’m just more a reflection of who we are.” Garguibo/SplashNews.com Kanye West Replaced Ariana Grande on SNL‘s Season Premiere After Singer Had to Drop Out The 21-time Grammy winner also appeared to foreshadow his choice earlier this week when he released a snippet of a song from his forthcoming album. “I’m givin’ up my slave name / I’m givin’ up my slave name,” he sings in the tune, which he played for employees at Fader on Thursday. During the song, he then went on to suggest that his children do the same. “Saint, you don’t really need a last name / North, you don’t really need a last name,” he said of his son and eldest daughter.
