Casey Affleck is set to host NBC's Saturday Night Live for the first time tonight, with musical guest Chance the Rapper, and here's how to watch it live online.

Affleck is making his SNL hosting debut Saturday night, at a key point in his career. The actor has been receiving huge critical praise for his role as an uncle who looks after his newly-fatherless nephew while battling his own demons in the new film Manchester by the Sea. Affleck won the Critics' Choice Award for Best Actor on Sunday and was just nominated for a Golden Globe and a Screen Actors Guild Award for the performance.

This is also a huge moment for Chance the Rapper. The hip-hop artist just received five Grammy nominations, including Best New Artist, Best Rap Album for Coloring Book, and Best Rap Performance for "No Problem". This is also Chance the Rapper's first musical appearance on SNL.

Meanwhile, Alec Baldwin will be back again as President-elect Donald Trump. The actor already teased his upcoming appearance on Twitter:

That "apple-agize" comment is probably a nod to Trump's most recent tweet (which has since been deleted), where the president-elect said that China stealing a United States Navy research drone was "unpresidented."

Saturday Night Live begins at 11:30 p.m. ET/PT on NBC and lasts until approximately 1 a.m. ET/PT.

If you cannot watch tonight's SNL on television, NBC has its own live stream on its website. You'll need to input your (or a helpful friend's) cable subscription information to gain access to it, though.

If you do not have a cable subscription, you still have one option. You can try a free trial of Sling TV, which has a live stream of NBC.

Of course, if you are patient enough to wait, most of the sketches and musical performances will be available to watch online Sunday morning, through Hulu, YouTube and NBC.com.
