You know you want it. Matt Damon's diaper bag? Julianne Moore's high chair? Random crap from Tori Spelling? You can have it. You just need to have the cojones to face all those other celeb-swag-desperate eBayers who are gonna bid their pants off for a chance at Elisabeth Hasselbeck's car seat.

The Johnson & Johnson's Celebrity Hand-Me-Down auction went live last night, so you're going to want to start stalking your preferred items now. Don't let Mariska Hargitay's Baby Adidas outfit get away!
