Season 45 of "Saturday Night Live" is starting with a bang, featuring a star-studded lineup of hosts and musical guests, led by the unexpected -- and sure to be triumphant -- return of one of the show's most famous alums.

On Monday, "SNL" revealed a partial lineup for the first half of the upcoming season, which will kick off on September 28 with Woody Harrelson hosting, alongside musical guest Billie Eilish.

That duo will be followed by "Bond 25" screenwriter (and Emmy-nominated "Fleabag" star) Phoebe Waller-Bridge and Taylor Swift on October 5; David Harbour and Camila Cabello on October 12; and Kristen Stewart (musical guest TBA) on November 2.

But it's the final emcee of 2019 that had fans buzzing those most on Monday: None other than Eddie Murphy is set to headline the December 21 episode, marking his first time hosting in more than 35 years. No musical guest has been announced yet.

Murphy shot to superstardom on "SNL," where he was a cast member from 1980 until 1984. The comedian is credited with revitalizing the series during that time period, and remains one of the show's most beloved former stars.

But since his departure from the series, Murphy has been almost entirely absent from Studio 8H, returning only for a brief, awkward appearance at the SNL 40 celebration in 2015. He was also slated to pop up in a sketch that evening, but ultimately bailed; if Murphy keeps his date with "SNL" in December, the episode will mark his first time actually performing on the show in more than three decades.

Our fingers are crossed for an epic evening. We can't wait for season 45 to start.
