Project Runway's Heidi Klum has said "auf wiedersehen" to her baby weight.
On Wednesday, she revealed her post-baby body as she joined Victoria's Secret supermodels Wednesday as they promoted the upcoming Victoria's Secret Fashion Show in NYC.
Klum, 36, welcomed daughter Lou Oct. 9.
She made her first post-baby appearance Oct. 31 at her annual Halloween bash in L.A., but kept her body covered up in a crow costume.
"I wouldn't say I'm back in the shape yet," Klum told Usmagazine.com at bash. "But I don't know. Everything changes when you get older. It was different when I was 31 with the first one. Now, being 36 with the fourth one, it's different."
"I don't exercise too much — I walk," she added. "I walk on the treadmill a little bit. I walk on the driveway. I'm very active with the children. When you have three children and two boys, they're very active. They want to do a lot of things. But you know when you breastfeed, when you eat right, you move around a little bit, that usually does the job."
Klum – who said she is hosting the annual Victoria's Secret fashion show but not walking in it – added that she'll gradually increase her workouts.
"For me, it always works to get back into it immediately," she told Us. "I think that if you wait too long, it kind of sticks on and it stays there forever. I have to be motivated."

Husband Seal said he is impressed with how amazing she looks after giving birth.
"She just has a knack for all of these things," he said. "She’s just one of those people – I say one of those people – and there isn't actually anyone like her. But she just has a knack for it. She's a person who can do pretty much anything. And I got used to that within a few months of knowing her. She's the 'it' woman. She can do anything."
As for their newborn, Klum told Us the baby looks "like both" her and Seal.
"It’s a mix," she said. "To be honest, they all look the same when they're little. They all have beautiful, full head of hair – black. Beautiful, dark eyes and full lips. They all do look the same in the beginning and then they kind of morph into their own faces."
