Fun for the whole family ... even fetuses! Kourtney Kardashian brought her brood to the annual Malibu Chili Cook-Off carnival on Saturday evening -- sone Reign in a vintage concert tee, daughter Penelope in an olive green army jacket, and son Mason not far behind in a tactical vest. Kourt herself was wearing high-waisted, wide-legged black trousers with a black tank and Doc Martins.

Also there for the fun was very pregnant Amber Rose with baby daddy Alexander "AE" Edwards. The pair are expecting their first child together -- her second, she also has son Sebastian, 6, with ex Wiz Khalifa -- in a month! Hope she didn't go on the roller coaster or the pirate ship ride with THAT baby bump!
