Klum, 46, was absent from her post at “America’s Got Talent” this week, said to be suffering from a common cold.
“There just isn’t one here,” she said, appearing to be speaking to her more than 7 million followers from her bed.
Klum said her symptoms include chills, fever, cough and a runny nose.
“I’m just not feeling good so that’s why I’ve stayed home — to not infect other people,” she said.
She added. “Stay safe, everyone. Stay home if you don’t feel good.”
“Modern Family” actor Eric Stonestreet filled in as a guest judge this week for Klum.
Klum co-stars on the reality competition series alongside Simon Cowell, Howie Mandel and Sofia Vergara. Terry Crews hosts.
