Lady Gaga as Rosaline Rotwood in "Wednesday."

Spoiler alert! The following contains details from Netflix's "Wednesday" Season 2, Episode 6.

Are you ready to go Gaga for "Wednesday"?

The second part of Season 2 of Netflix's smash Addams Family hit is now streaming, and it has 100% more Lady Gaga onboard than in the first part of the season that arrived in August.

The pop star's fans were sorely disappointed when the first four episodes of the series' second season debuted without an appearance by Gaga, whose guest-starring role in the gothy drama has been teased by Netflix for months.

How does Lady Gaga show up in 'Wednesday'?

Lady Gaga shows up in Season 2, Episode 6, as deceased Nevermore professor Rosaline Rotwood. Wednesday (Jenna Ortega) goes to Rosaline's grave searching for a way to retrieve her broken psychic powers . There, she encounters Rosaline's spirit after reciting a mystical chant, and Gaga shows up all ethereally clad in white with platinum blonde hair and eyebrows.

While Rosaline gives Wednesday a quick supernatural power boost, it comes at a cost: her peppy roommate Enid (Emma Myers) interrupts the séance and she and Wednesday wind up swapping bodies "Freaky Friday"-style (or rather, Freaky Wednesday). Rosaline shows up again later in the episode to tell Wednesday that if she and Enid don't find a way to reverse the body swap by dawn (and find a way to understand each other, as with all similar stories), they'll both die.

Before they can focus on themselves, the pair has to try to save Wednesday's little stalker/mini-me Agnes (Evie Templeton) after she discovers and follows Tyler (Hunter Doohan), his mother Francoise (Frances O'Connor) and crazed zombie Uncle Isaac (Owen Painter). The mixed-up Wednesday/Enid show up, save Agnes and Wednesday "wolfs out" in Enid's body, sending Tyler and his messed-up family packing (and probably making them pretty angry in the process).

The roommates finally understand each other, sharing some heartfelt sentiments at Rosaline's grave before swapping back to their appropriately pigmented selves. However all is not well: Wednesday's premonition about Enid's death has been swapped with one that says an Addams must die.

Who else is in 'Wednesday' Season 2 cast?

Gaga's big Episode 6 cameo was hotly anticipated, but she's not the only big name on the docket this season. Other guest stars include Catherine Zeta-Jones, Luis Guzmán, Steve Buscemi, Billie Piper, Christopher Lloyd, Heather Matarazzo, Dame Joanna Lumley, Fred Armisen, Isaac Ordonez, Haley Joel Osment and Thandiwe Newton.
