Sexiest Halloween Costumes: Gigi Hadid, Jennifer Lopez, Jenna Dewan Tatum and More Stars

Tricks and treats! The possibilities for Halloween costumes are endless, and celebrities are never afraid to step out of their comfort zones in jaw-dropping getups. As the spooky holiday quickly approaches, Us Weekly Video rounds up the sexiest costumes the stars have worn over the years, as seen in the video above.

Gigi Hadid, 2015

Tell me about it, stud! The supermodel, 21, turned heads at Heidi Klum's annual Halloween party in October 2015 when she dressed as Grease leading lady Olivia Newton-John's beloved character, Sandy Olsson. Hadid stunned in a skintight black ensemble that showed off her svelte figure and enviable abs. She paired the look with red pumps and red lipstick, and wore her golden locks in curls.

Jennifer Lopez and Casper Smart, 2015

The "Jenny From the Block" singer, 47, and her on-again, off-again boyfriend, 29, also partied at Klum's bash last year, where they spooked fellow attendees in matching skeleton costumes. Lopez looked drop dead gorgeous (pun intended) as she showed off her ample cleavage in a plunging black dress and white face makeup. Smart, meanwhile, opted for a black button-down shirt and black pants, rocking equally frightening skeleton makeup. (J. Lo's look was even the inspiration behind Kylie Jenner's 2016 Halloween costume!)

Jenna Dewan Tatum and Channing Tatum, 2015

Happy Halloween!!!!!!

The Step Up actress, 35, looked super sexy alongside her husband, 36, at the 2015 Casamigos Tequila Halloween Party as they donned coordinating The Cat in the Hat costumes. The hunky actor was adorable in a traditional costume, while his wife dressed up as a more sultry version of the beloved Dr. Seuss character.
