Sorry Heidi Klum, but 2019 might just have a new Halloween Queen!
The biggest Halloween trend this year in Hollywood? Celebs dressing up as other celebs. Sure, some stars donned costumes of famous characters, but even more decided to dress as the actual celeb.
The Real Housewives of Beverly Hills star Lisa Rinna and Brad Goreski both took inspo from Jennifer Lopez's iconic Gucci dress, while Neil Patrick Harris and husband David Burtka dressed as the Olsen twins.
Lily Allen, meanwhile, paid Halloween homage to Kris Jenner, and, in a true mic-drop moment, Ciara and Russell Wilson recreated an iconic Beyoncé and Jay-Z moment flawlessly, and Jessica Biel dressed as husband Justin Timberlake from his *NSYNC days. Well played.
A few other celeb-on-celeb costumes included Miley Cyrus and Cody Simpson as Perri Lister and Billy Idol, Kevin Hart as The Rock, Love Island host Arielle Vandenberg as wedding Justin Bieber, HAIM as Hanson (truly inspired), and former Bachelor Nick Viall as future Bachelor Peter Weber.
But there was one celebrity that managed to inspire the most costumes (and black tears) this Halloween season...and it was Billie Eilish! (Sorry Post Malone, you're so 2018.)
The "Bad Guy" singer had not one, not two, not three but six celebs dress up as her, rocking her signature black hair and chain necklaces.
Nina Dobrev dressed up as the 17-year-old breakout star at the Casamigos Halloween Party last weekend with an all-orange sweat-suit and green hair, while British songstress Anne-Marie's take on her look even impressed the singer.
"This s--t tripping me out," she captioned a video of Anne-Marie's on Instagram, calling her look, "Very accurate."
Billie also weighed in on The Good Place star Jameela Jamil's look, which she sported at a Spotify event, saying it also was accurate.
Jameela wasn't the only sitcom star to dress as the "Bury a Friend" singer as Brooklyn Nine-Nine's Stephanie Beatriz rocked a neon-green look for the holiday.
Model and actress Poppy Delevingne was another celeb to take inspo from Billie, sporting black and blue hair, black tears and safety goggles as the ultimate accessory. Her Instagram caption? "It's HALLOWEEN, duh."
But the most adorable take on Billie's signature look was Harper Beckham, the 8 year-old daughter of David and Victoria Beckham, who dressed as her favorite artist to go trick-or-treating with the family.
"Harper Seven LOVES @billieeilish (and a heavy eye!," Victoria captioned a pic of Harper's makeup on Instagram.
She wore a blue wig, black tears and a mostly white sweat-suit a la the "When The Party's Over" music video Billie, completing her look with gold chains and the poses to match.
