AceShowbiz - Celebrity couple Jessica Biel and Justin Timberlake stole the show at a star-studded Halloween bash in Los Angeles. The actress dressed up as her husband during his NSYNC heyday and the male singer played along dressing up as her microphone.

Biel donned a curly blond wig, metallic turquoise jumpsuit, white sneakers, diamond stud earring, and little blue sunglasses. Meanwhile, Timberlake was decked out in black from head to toe. He donned a huge helmet and had an "on/off switch" hung around his neck.

The couple even brought an entourage of guys to act as Timberlake's bandmates JC Chasez, Chris Kirkpatrick, Joey Fatone, and Lance Bass. The men wore wigs and neon-colored jackets, and finished off their boyband looks with over ear microphones.

The party took place at Casamigos co-founder Mike Meldman's Beverly Hills home on Friday, October 25. Channeling her inner disco queen in colorful outfit, Cindy Crawford came with her husband Rande Gerber, who's also a Casamigos co-founder.

"The Real Housewives of Beverly Hills" star Lisa Rinna also turned heads as she recreated Jennifer Lopez's iconic look at the 2000 Grammy Awards. The reality TV star showed off her cleavage in a replica of J.Lo's Versace green floral dress.

Paris Hilton channeled Playboy bunny, Patrick Schwarzenegger dressed up as Austin Powers, Nina Dobrev as Billie Eilish, Stephen Amell showed up as a hotdog, Ryan Phillippe dressed up as Han Solo, and Laverne Cox sexed up in a warrior leotard. Also spotted among the high-profiled guests were Kaitlynn Carter and Gerard Butler.

"Ohhhhh behave. U look smashing baby," Schwarzenegger captioned a picture of him and his girlfriend from the bash. Meanwhile, Carter posted a group photo of her girlpals and wrote, "and the night is still young..."

Cox remembered a last-minute shopping before the party, "I had so much frantic fun shopping for this look by myself just a few hours before the party started. And what a lovely surprise to find this one of a kind bustier and metal 'breast belt.' "
