Stars Who Dressed Up as Other Stars on Halloween

KIM KARDASHIAN WEST & JONATHAN CHEBAN: CHER & SONNY

In one of her many costume changes ahead of Halloween 2017, the business mogul enlisted BFF Jonathan to serve as the Sonny Bono to her Cher circa the 1970s.

KOURTNEY KARDASHIAN & KIM KARDASHIAN WEST: MICHAEL JACKSON & MADONNA

Looks like Halloween 2017 was an excuse to pay homage to music icons — if you were part of the Kardashian crew, that is. The Kardashian sisters dressed up as the King of Pop and Madge, respectively, for a costume party.

KARLIE KLOSS: MARILYN MONROE

The supermodel put her platinum hair to good use as she transformed into Monroe, debuting her look on Instagram and accompanying the snapshot with a quote by the actress. "Imperfection is beauty, madness is genius and it's better to be absolutely ridiculous than absolutely boring," she wrote.

ELLIE GOULDING: DOLLY PARTON

Hello, Dolly! Goulding got a little bit country as she stepped into the boots of the music legend at the 2017 amfAR and The Naked Heart Foundation Fabulous Fund Fair.

KATY PERRY: HILLARY CLINTON

Perry channeled the presidential candidate for 2016's festivities, opting for prosthetics and a crimson pantsuit reminiscent of the White House hopeful's signature style.

BEYONCÉ: SALT-N-PEPA

With the help of daughter Blue Ivy, the "Hold Up" singer pulled out all the stops, paying homage to the hip-hop girl group Salt-N-Pepa from the music video for "Push It." Beyoncé sported a black bobbed wig, gold chain and oversized jacket while Blue appeared to wear a white bodysuit, high-top sneakers and a jacket to match her mom's.

KYLIE JENNER: CHRISTINA AGUILERA

The starlet channeled old-school Xtina in the singer's 2002 music video for "Dirrty." Jenner opted for blonde hair, a nose piercing and chaps to complete her look.

DEMI LOVATO: SELENA QUINTINILLA

Lovato channeled Quintanilla, her fellow Texan icon and the late Queen of Tejano music, for Halloween — and the resemblance is uncanny.

NINA DOBREV: RYAN LOCHTE

Dobrev copied Ryan Lochte's Rio Olympics look in 2016, with friend Lane Cheek accompanying her as swimmer Jimmy Feigen.

MILEY CYRUS: LIL' KIM

Her VMAs look became one of the hottest costumes ever, so the cheeky singer took it back to the awards show for her own look, donning a spot-on copy of the pint-sized rap star's equally risqué VMAs outfit from over a decade ago.

QUEEN LATIFAH: OPRAH

The actress-turned-talk-show-host paid homage to the undisputed queen of daytime TV during her Halloween episode.

MATTHEW MORRISON: ANDY WARHOL

KELLY OSBOURNE: CHRISTINA HENDRICKS

Christian Siriano made the lucky star an identical replica of the red-carpet dress he designed for the flame-haired Mad Men actress, but the style expert admitted she needed a little help to achieve the actress's famous curves, confessing

on Instagram, "I had to wear 3 bras!!"

CINDY CRAWFORD & RANDE GERBER: SLASH & AXL ROSE

The usually glam supermodel and her handsome hubby stepped back in time – and into their skinniest jeans – to morph into the big-haired '90s-version of the Guns 'n' Roses rockers.

ELLEN DEGENERES: NICKI MINAJ

The daytime talk host let it all hang out on her Halloween show, showing off her "boom booms" and her "super bass" as the voluptuous rap star.

"I got u babe," cooed the A-list stylist in this loving Instagram shot, harking back to her favorite fashion era, the '70s, to channel the folksy singing duo.

PARIS HILTON: MILEY CYRUS

The leggy socialite took her inspiration from one of the most talked-about VMAs performances ever, donning a copy of the controversial singer's famous furry leotard to make her own show-stopping entrance at the Playboy Mansion Halloween party.
