This is Bateman's second time hosting the show, while this is the country singer's second chance at performing at Studio 8H.
Wallen was first scheduled to make his SNL debut on Oct. 10, but was replaced by Jack White after violating the show's COVID-19 protocols. At the time, Wallen apologized and revealed that the show's creator, Lorne Michaels, told him, "We'll find another time to make this up."
"I’m not positive for COVID, but my actions this past weekend were pretty short-sighted and they’ve obviously affected my long-term goal and my dreams," Wallen said at the time. "I know that I put [the show] in jeopardy, and I take ownership of this."
In an interview with ET, Wallen said he's "just gotta be aware that most of my actions... will be brought to light."
"I don't think I really, truly understood the reach that I have," he added to ET. "It's all hit me over quarantine."
SNL airs live, coast-to-coast, at 11:30 p.m. ET, 8:30 p.m. PT on NBC.
