Woody Harrelson was the guest host on the season premiere of Saturday Night Live, and the musical guest was none other than young newcomer and chart-topper Billie Eilish. This was her first appearance on SNL and based on the fan reactions I think it’s fair to say she knocked it out of the park. Official videos were just posted, scroll down to see both performances.

Check out this great video showing the behind-the-scenes of the “bad guy” filming. Amazing that they did this live.

Creating Saturday Night Live: Billie Eilish “Bad Guy” Performance – SNL

She did “bad guy” first with a rad effect in which she was looking like she was climbing the walls. They pan back to show you how they did it, but it’s a great trick and definitely works.

Here’s “i love you” with her brother Finneas O’Connell.

As a promo for this episode, Woody and Billie were shown arriving to the new season like it’s the first day of school. Hilarity sorta ensues, but not really. Standard fare for the first showing on any SNL bit.
