Shameless self promotion runs in the family, eh?

Khloe Kardashian took part in a little bit of shameless promotion when she shared the above photo of her nieces, North West and Penelope Disick, holding a holding a copy of her new book, "Strong: Looks Better Naked."

“I can't stop smiling when I look at this photo!" she captioned the shot. "I love my little ladies!! They were so excited and kept screaming ‘KoKo! KoKo!’ North calls me ‘KoKo Loco.'" We think it's a little loco for the little girls to be clutching a copy of a book where there auntie appears naked, but keep in mind, their family isn't like yours!

Khloe had been busy promoting her new book, but she was forced to cancel a recent signing after coming down with a infection that required antibiotics and painkillers to treat. Ouch! Feel better Koko Loco...
