Saturday Night Live's Nov. 6 episode is going to be one with quite a few wacky hair jokes. On Tuesday (Oct. 13), the long-running NBC show announced that Republican presidential candidate Donald Trump will host the fourth episode of season 41, with some musical accompaniment from Sia.

SNL announced the lineup for its upcoming episode on its Twitter, revealing that Trump will be taking the stage alongside Sia. He'll be the fourth host of the season, following this season premiere's Miley Cyrus, Amy Schumer and Tracy Morgan, who is set to return to SNL on Saturday (Oct. 17).

Meanwhile, Sia will be joining the season 41 ranks of Cyrus, The Weeknd and Demi Lovato as the fourth musical guest. The stage will be a comfortable place for her, she performed on Saturday Night Live just last season when Kevin Hart hosted. With some help from her frequent performance partner Maddie Zeigler, she performed her 1000 Forms of Fear hits "Chandelier" and "Elastic Heart."

She also appeared on the SNL 40 special last winter alongside Kanye West and Vic Mensa to perform the Swish track "Wolves."

Sia will be appearing on SNL this time presumably to promote her new album This Is Acting. Though her new LP has yet to receive an official release date, the lead single "Alive" has already been released. Along with the theme of her album - which features songs she wrote for other artists - "Alive" was written for and in the point of view of Adele.
