Supermodel Heidi Klum is pregnant for the fourth and final time.

The 36-year-old baby machine and her husband, Seal, have decided this will be the last baby for the celebrity couple.

Together they already have three children: sons Henry and Johan and daughter Leni.

Heidi says it ends here.

     "Four is perfect.  Three is a lot but four? It's a lot of work.  We're hands-on,
      and we feel like this is what we can handle."

The Project Runway host and judge, who is having a girl, admits she and her husband are having trouble naming their unborn child due in October.

    "Because we know it's going to be our last baby, it's way harder.  We're

     going to wait until we see the baby and hopefully the light bulb will come
     on and then it'll be like ding-ding-ding!"

Any suggestions?
