It's been one month since Kourtney Kardashian and Scott Disick got back together and the couple has been continuing to spark pregnancy rumors ever since!

The on-again, off-again couple stepped out together yesterday for a family trip to Disneyland to celebrate the birthdays of their sons, seven-year-old Mason and and two-year-old Reign — they also share four-year-old daughter Penelope together — and the mom of three wore a baggy sweatshirt during the outing which seems like a strategic fashion move to hide her possible growing baby bump.
