Ja, Heidi Klum expecting another child

"Project Runway" host Heidi Klum is not only expecting a change in network, but a change in her family's numbers.

The 35-year-old supermodel and her husband Seal confirmed that she's pregnant with their fourth child, reports Usmagazine.com

The couple, who married in Mexico in May 2005, already have three kids: 4-year-old daughter Leni (whom Klum had with Flavio Briatore), and sons Hrnry, 3, and Johan, 2.

The upcoming season of "Project Runway," now on Lifetime, has already been taped and thus should not be affected by Klum's pregnancy.
