He Had To Listen To The Dr.'s Orders: Watch Kendrick Lamar Accept The ALS Ice Bucket Challenge From Dre

K-Dot nominated Serena Williams, Ellen DeGeneres and Samuel L. Jackson.

Kendrick's the latest in a lengthy list of celebs (and non-famous people) to accept the challenge -- which looks to raise both awareness and money for ALS research -- and he joins the ranks of Justin Bieber, Katy Perry and Miley Cyrus, among others.

Serena Williams, Ellen DeGeneres and Samuel L. Jackson, you're up.
