Justin Theroux took his ice bucket challenge on Saturday and nominated his fiancée, Jennifer Aniston. 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, who has already taken the challenge herself.
