Heidi Klum's Coldwater Canyon Bump

An expectant Heidi Klum was spotted playing with her three children - Leni, 5, Henry, 3 ½, and Johan, 2 ½ - at Coldwater Canyon Park in Beverly Hills on Monday (July 27). At one point, little Leni had to help mom get up which made Heidi laugh. The Project Runway host and her hubby Seal are expecting their fourth child - a girl - in October.

Reportedly, the 36-year-old supermodel sparked a water balloon war between parents and members of the paparazzi earlier this month when the snappers refused to leave her and her kids alone during a visit to a NYC playground. Fellow parents at the playground were not pleased with the prying shutterbugs and asked them to leave. When the paps ignored their requests, the angry parents began pelting them with water bombs, forcing Klum to flee the chaos. Could it have been this outing that caused all the commotion?
