Today is Kanye West's 45th birthday, but no one from the Kardashian-Jenner family has yet used social media to wish Kim Kardashian's ex-husband a happy birthday. Over the years, the reality TV family has sent birthday wishes to exes and ex-partners, including Kanye, who got messages from Kim and her sisters on Instagram last year. Despite not showing love for Kanye online, Kim will celebrate his birthday with North, 8, Saint, 6, Chicago, 4, and Psalm, 2. A source told HollywoodLife.com that Kim has been taking the kids shopping for birthday gifts for their father, and there are plans for them to spend the day with him. Kim would never keep the kids from seeing their father, the source says.
