Kourtney and Kim's daughter Penelope and North West got excited when they saw their favourite aunt Khloe Kardashian's recently-launched book 'Strong Looks Better Naked' in a book store.
The 'Keeping Up with the Kardashians' star took to her Instagram posting a picture of her two thrilled nieces standing in a book store and holding their aunt's new book, along with a caption "I can't stop smiling when I look at this photo! I love my little ladies!! They were so excited and kept screaming KoKo! KoKo! North calls me KoKo Loco", the Mirror reported.
Before this, Khloe apologised her fans for not showing up at her book launch due to bad health.
