The ALS Ice Bucket Challenge to raise awareness for ALS (Amyotrophic lateral sclerosis), or Lou Gehrig's disease, has raised over $70 million dollars as of Sunday, Aug. 25, and thanks to continued celebrity support, the ALS Association should continue to see donations pour in.

For today's roundup, we finally see Eminem and Rihanna taking the challenge together as they close out The Monster Tour in Detroit. Jennifer Aniston also hilariously braves the cold, along with other A-list actors such as Reese Witherspoon, Kate Hudson, Bradley Cooper, Kristin Chenoweth, Jason Sudeikis, Olivia Wilde and Neil Patrick Harris.

Enjoy! And remember, you can become involved with ALSA's mission by visiting their website.
