Chasing after four kids doesn’t leave a ton of time for glamorous updos and blowouts–just ask Heidi Klum. The Project Runway star and mom to four little ones under the age of six has debuted a noticeably more laid-back new do. Known for her lustrous, flowing locks, which have been styled in every possible way from a pin-straight blowout to bouffant updo, the star stepped out last week for some playtime with kids Leni and Johan in a slouchy sweatshirt, skinny jeans and sneakers–accessorizing with a shaggy new bob. The shoulder-length cut with heavy, blunt bangs has a low-maintenance, wash-and-go feel to it–a totally appropriate look for someone who spends much of her time with toddlers–and yet, on Heidi, it looks positively runway ready. Tell us: What do you think of Heidi’s new effortlessly chic hairstyle? –Marissa Patlingrao Cooley
