Celebrities love a good dress-up holiday and when it comes to going all out, Halloween comes tops. Just check out Jessica Alba and her husband Cash Warren at George Clooney's Casamigos Tequila Halloween Bash on Friday night (Oct. 30).

The pair was spotted at Clooney's Halloween party in Beverly Hills dressed up as characters from two iconic films. Alba, 34, dressed up as Romy White, Mira Sorvino's character from the 1997 hit comedy Romy and Michele's High School Reunion. While Warren, 36, dressed up as Tom Cruise's character in the classic Top Gun — Pete "Maverick" Mitchell.

Alba's ultra blonde shoulder length locks were perfect alongside her light metallic blue mini-dress and in true Romy style, a matching iridescent purse. Of course, there can't be Romy without Michele and Alba's good bud Kelly Sawyer played the part of Michele Weinberg, Lisa Kudrow's character. Sawyer wore a light pink metallic dress with white fur trim, a shimmering choker, and high pony-tail. They both wore chunky gold heels and metallic eye-shadow, completing their true-to-the-film costumes.

Alba took to Instagram to show off their costumes. Posting, "@kellysawyer n I invented post-its." (See, below.)

Hubby Warren's costume was also spot-on. He wore a khaki jumpsuit, complete with patchwork, aviator sunglasses, and black boots. Warren also took to Instagram. He captioned a group photo: "How I feel right now vs how I felt last night couldn't be more different. Happy Halloween." (See, below.)

With more Halloween parties tonight, we can't wait to see what the celebrities will dress as. Stay tuned!
