Comedian Kevin Hart returns to host his third "SNL" episode. His upcoming film, "Jumanji: Welcome to the Jungle," will open Dec. 20 and also stars Dwayne Johnson, Jack Black, Karen Gillan and Nick Jonas. Hart is also currently headlining his comedy tour, "The Irresponsible Tour."

Foo Fighters will return for a seventh time as musical guest, tying the record for most "SNL" appearances by a rock band. Debuting at #1 in the U.S. and more than a dozen other countries, the band's latest album, "Concrete and Gold," was released Sept. 15. The Foo's current world tour continues to sell out stadiums and arenas through 2018.
