Work it, girls! Check out Kim and Kourtney Kardashian at NBC in NYC earlier today - the reality stars are busy promoting their new book Kardashian Konfidential.

Sister Khloe revealed on The View this morning that she lost her virginity at 14 to an 18-year-old and almost felt "conned" by her sex partner. "I felt so disgusted with myself," she said. "I stopped talking to him and actually didn't have sex for three years after that because I knew I was young and I knew I wasn't ready."

Meanwhile, Kim continues to claim she's "single" and "having fun." But what about Gabriel Aubry?
