Jennifer Garner, Miranda Kerr, Beyoncé & More Stars in Halloween Costumes

Hey there, I’m Karli. After a festive weekend, Hollywood kept the Halloween spirit going on Monday. Take a peek at some of the cutest costumes in today’s PopSugar Rush! Jennifer Garner’s witch costume couldn’t conceal her growing baby bump as she took a walk in LA on Halloween. Across the country, a pregnant Beyoncé buzzed around New York as a bumblebee. Then there was fellow mom-to-be Hilary Duff, who donned a couple’s burglar costume with husband Mike Comrie. There were plenty of pregnant stars out and about for the holiday, but perhaps Jessica Simpson’s “mummy” costume and big “mommy” announcement was the most talked about. She posted a “family portrait” with fiancé Eric Johnson, as did Britney Spears with her kids, mom and boyfriend Jason Trawick. Heidi Klum held her annual Halloween bash in NYC last night, and while she already showed off a skinless body costume over the weekend, this time she and husband Seal went as matching monkeys. Heidi’s party always draws a star-studded crowd. This year, a Toddlers and Tiaras dressed Fergie attended. But there was competition across town — Miranda Kerr hosted a Victoria’s Secret party and went as a seriously sexy circus ringleader. Meanwhile, Lauren Conrad went the cute route in LA, posing at a party as Minnie Mouse, complete with ears made from her own hair! With all those fun parties and fabulous costumes, it sure seems that the stars had a very happy Halloween!
