The Skims founder, 40, took to social media to share a picture of the estranged couple in happier times aboard a private plane with three of their children – North, 7, Saint, 5, and their daughter Chicago who was an infant at the time the photo was captured. The two have since welcomed son Psalm as well.
“Happy Birthday. Love U for Life!” Kardashian wrote in a tweet for the Yeezy honcho’s 44th birthday, adding a red balloon emoji.
The “Keeping Up With the Kardashians” star also shared a throwback couple’s photo, a pic of West with all four kids, and a children’s portrait of a young West from 1987 on her Instagram Story.
Khloé Kardashian, 36, also gave a birthday shout-out to West on Tuesday in an Instagram post. “Happy birthday to my brother for life!!!” she wrote next to a picture of her wading in the ocean during a trip with West, Kim and Khloé’s on-again, off-again boyfriend Tristan Thompson.
