Kim Kardashian took to Instagram to share a photo of herself in blue contacts Sunday. The 34-year-old "Keeping Up with the Kardashians" star sported the accessory in honor of husband Kanye West's performance of "Wolves" on "Saturday Night Live." The 37-year-old rapper closed a "Jesus Walks" and "Only One" medley with the new track for the NBC program's 40th anniversary special. Kardashian captioned pictures of herself and West with blue eyes "Wolfie" and "Wolves," respectively. The song hails from the rapper's upcoming seventh studio album. Kardashian and West welcomed their first child, daughter North West, in June 2013, and married in May 2014. The reality star made headlines last week for dressing her daughter in fur, and again when North threw a tantrum at West's New York Fashion Week show.
