Karl Lagerfeld has launched another vicious verbal attack on pregnant supermodel Heidi Klum — even taking a dig at her crooner hubby Seal.

“I don’t know her. Claudia Schiffer doesn’t know her. She was never in Paris, we don’t know her,” the catty Chanel designer quipped this week. “I am no dermatologist but I wouldn’t want his skin,” Lagerfeld added of Seal. “Mine looks better than his. He is covered in craters.”

In February, Karl cynically remarked that the longtime Victoria’s Secret model and Project Runway host is “too fat” for the runway.

What the heck is your problem, Lagerfeld?
