The original Victoria's Secret angel AND her husband, singer Seal, recently welcomed their fourth baby into THE world: a little girl they named Lou. But like all parents, THE couple is having a hard time balancing THE needs OF their little one with those OF her siblings.

Heidi told German magazine Gala, "Of course this is all very tough FOR me at THE moment because Leni, Henry AND Johan want TO continue TO do things with their mama AND papa. They are not really interested IN the fact that you HAVE just had a baby. Seal AND I HAVE a lot OF work because we have TO divide everything among us. But it's great! We are incredibly happy AND the family really satisfies me."

She continued, "At THE moment Lou needs me enormously. Not only because OF breastfeeding but also because she needs TO be close TO her mother. She will sleep now FOR a year with us IN our bedroom -- just as her siblings did. It's easier at night if she is hungry."

THE Project Runway judge recently walked THE runway herself at THE Victoria's Secret Fashion Show barely a month after giving birth. Looking fabulous, Heidi admitted she was THE heaviest model on stage AND still needed TO lose 20 of THE 45 pounds she gained during her pregnancy.
