Justin Theroux took his ice bucket challenge [1] on Saturday and nominated his fiancée, Jennifer Aniston [2]. On Sunday, she shared her chilly video, which she filmed with the help of Justin, who took his time pouring a bucket of freezing water over her head. It wasn't all torture, though, since Justin gave Jennifer a sweet kiss after the challenge was over. The charitable fun will continue since Jennifer nominated Howard Stern and her pal Chelsea Handler [3], who has already taken the challenge herself.
