One Direction performs at the 2014 iHeartRadio Music Festival on Sept. 20, 2014.

One Direction will close out Saturday Night Live's 2014. 

The band will be the musical guest for SNL's holiday episode Dec. 20, joined by host Amy Adams. The band has performed on SNL before -- most recently with host Paul Rudd last December, when the whole band memorably participated in a sing-off during Rudd's monologue. 

Fans will be thrilled to know 1D will be all over NBC that week. In addition to SNL, the guys will have their very first U.S. prime-time special Dec. 23.
