Reality TV star, Kim Kardashian and rapper, Kanye West’s daughter, North West, turned 4-years-old yesterday. The proud mama shared photos of the huge balloon surprise set up for her daughter in their California home (photo on the right), while her aunt, Khloe Kardashian shared a photo of the birthday girl with her cake at somewhere that looks like Chuck E. Cheese’s (photo on the left). Happy birthday, Nori!
