No makeup necessary! A makeup-free Kourtney Kardashian stepped out looking extremely casual in sweatpants, a zip up hoodie, and a beanie with son Mason, 3, and daughter Penelope, 1, on Sunday, Nov. 17. 

Kardashian, 34, took her tots out for some frozen yogurt at Menchies Frozen Yogurt in Los Angeles near their home. Father and long-time boyfriend Scott Disick was no where to be found as Kardashian walked the kids around the shop, picking out treats.

Kardashian's laid back look is a direct contrast to her dolled up style in a recent Terry Richardson photoshoot for the Kardashian Kollection Lipsy launch. The mother of two also frequently posts pictures of herself dressed to the nines on Instagram.  

Disick recently suffered the tragic loss of his mother, Bonnie Disick, and has been absent at several recent Kardashian family outings including Kanye West's Oct. 21 proposal to Kim Kardashian and the family trip to Six Flags Magic Mountain to celebrate Kendall Jenner's 18th birthday in late October.
