Megan Fox, Machine Gun Kelly at the Casamigos Halloween Party

Nothing comes together better than tequila and Halloween.

Plenty of celebrities showed up at Casamigos’ Halloween party at their private residence in Beverly Hills on Friday, officially kicking off the costume festival for the weekend.

Megan Fox and longtime beau Machine Gun Kelly appeared as Pamela Anderson and Tommy Lee, who became the infamously first known couple whose homemade sex tape was leaked to the public in 1995.

Meanwhile, the newlyweds Josh Duhamel and Audra Mari transformed into the oil baron J. Howard Marshall and his wife Anna Nicole Smith, who at the age of 26 married an 89-year-old billionaire 14 months before her death in 1995.

The choice of the costume in which the 49-year-old alum “All My Children” hunched on the walker also seemed to laugh at how the actor threw his back while dancing the night before the two were about to tie the knot, landing him in the ER.

Among those who led fictional Hollywood icons – or used its broader ethos of famous characters – were Tyga in an ET mask; The actor “Arrow” Stephen Amell and wife Cassandra Jean Amell as Wilson playing volleyball from “Castaway” and the title survivor of the plane crash, played by Tom Hanks.

Jordan Gerber appeared as Trinity from The Matrix, while Rebel Wilson and her group, including Ramon Agrum’s girlfriend, disguised as Barbie and Kens out of the box.

No one missed the party, Paris Hilton arrived as Sailor Moon.

Meanwhile, Kylie Jenner showed her “Bride of Frankenstein” costume on Instagram. It is not clear if she participated in the event.
