Talk about the ultimate buzz kill ... Hilary Duff was crying over spilled couture ... 'cause her designer bag took a soaking before she even got her first sip of coffee! Hilary hopped on IG to show the crime scene ... her Balenciaga’s contents all stained latte-brown, basically turned into a sad to-go cup … with the guilty, empty coffee cup sitting right next to it. Hilary said the whole disaster struck before she even got her first sip ... and yeah, that’s definitely a latte to deal with
