Khloé Kardashian has defended her sister after a fan suggested Kim Kardashian’s daughter isn’t her biological child, reports People.com. On Sunday, Kim shared a photo of herself as a child with the caption, “Baby K (sic).” Khloé stepped up for her sister and told the Instagram user, “If you don’t really know about someone’s situation then maybe you shouldn’t comment. Try informing yourself first before you make such silly statements doll.” She continued, “Your passive wanna be petty comment is simply uneducated. Chicago is completely Kimberly’s biological child. Praise the lord she was able to have a surrogate and that we are blessed with sweet gorgeous Chi Chi (sic)”
