Jennifer Aniston & Fiance Justin Theroux ALS Ice Bucket Challenge- See Lovebirds Get Drenched For A Good Cause

The ALS Ice Bucket Challenge is still in full swing, and soon to be married couple Jennifer Aniston and Justin Theroux are just two of the latest celebrities to participate. The viral videos have been burning up on social media for the last month as nominees dump freezing cold buckets of water over their heads before challenge others to do the same thing to raise money and awareness for ALS.

Actress Jennifer Aniston stepped up to the plate and anxiously waits for the water to be dumped over her head as she nominates her besties Courtney Cox and Chelsea Handler, as well as Charlie Downey and Howard Stern. She also says she is making a "huge ginormous donation," and persuades everyone watching the video to also make donations to the ALS Association.

Justin Theroux, who not only nominated Aniston during his own ice bucket challenge, also is the one who gets to dump water on the former Friends actress. He takes some sweet enjoyment in the dumping, as he slowly pours the water over his fiancée's head.

You can hear Aniston jokingly saying, "This is the worst, take it away," as she walks out of the camera frame.

Theroux also participated in the challenge earlier this week when he accepted the nomination from Jason Bateman.

The star of the HBO series, The Leftovers in turn challenges Jennifer Aniston mainly because she isn't there to see him take the freezing cold water over his head. The water numbs him so much that he mouths the words, "I can't talk," after getting drenched from head to toe.
