Little Big Sister! North West steps out for the first time since becoming a big sister..

Awww..she's such a cutie! But she seems to have had to take the back seat as Mum Kim Kardashian tends to her little brother.

 North West was photographed with Aunt Kourtney and cousin Penelope as they headed to a party rocking this lovely look..

She's such a  Lil Diva!
