It's been nearly three months since Kim Kardashian's assistant announced that the reality TV star would be taking "some much needed time off," but Kim is officially back on social media. After sharing an intimate home video and an adorable photo of her family on Tuesday, Kim posted a precious shot of her and her son, Saint West, on Instagram on Wednesday. Along with the cute snap, the 36-year-old wrote, "My son ❤." In addition to returning to Instagram, Kim also popped back up on Twitter and has been replying to fan tweets. Welcome back, Kim.
