Everyone keeps asking what I'm gunna be for Halloween – well, after working and running all over LA for 12 hours straight I've decided to be an exhausted chick playing candy crush and listening to music on the couch this year – fortunately I have everything for this costume readily available @monsterproducts

Happy Halloween from the set of #DeadlyMist in #Jiangmen #China I hate missing this holiday cuz there is nothing better than sitting at home and watching kids faces light up when you give them the extra big #Hershey bar as a treat. #BayArea #Halloween #MissingFamily&Friends #Movie #Filming #China #Acting #LiveYourDreams
