The "Flipping Out" star said on his radio show that the school's headmistress called to tell him that his daughter, Monroe, isn't welcome back at school.
"I said, 'Look, I am so sorry. What can I do to make this right?'" he said of his conversation with the headmistress.
But it didn't work.
Lewis said his daughter's expulsion was actually his fault after he made some negative remarks about the school on air, criticizing its back-to-school night. He said he also once talked about other parents on his radio show, which apparently caused some consternation.
"I mentioned the first names," he said. "I didn't mention the last names. I never mentioned the name of the school. Somebody really rallied and got everybody together and everybody fired up to get Monroe expelled."
Now, Lewis is speaking out about the incident, saying he can't believe his actions led to Monroe losing her place.
"I said, 'I cannot believe that this is the Montessori way,'" he said.
Most of all, he said he's frustrated he received no opportunity to make things better.
"You don’t get to make amends. There are no second chances, no warnings — nothing."
He added that he's learned a lesson as well.
“I take full responsibility. ... I am really, really sorry. I feel terrible about what happened. I know how it has affected Monroe. I will never do this again.”
