Bravo's Andy Cohen, known for his tongue-in-cheek commentary, admitted he should have zipped his lips regarding the Duchess of Cambridge going MIA last year.

Cohen addressed the matter during an episode of Sirius XM's 'Andy Cohen Live,' the first show since Princess Kate's announcement of her recent diagnosis of cancer.

"I just want to say, I am heartbroken by the news about Princess Kate, and I think someone on Sky News called me a numpty during that whole conversation — and they were right," Cohen, 55, said on the show Monday. "And of course, I wish I had kept my mouth shut and we are all praying for Princess Kate and King Charles."

"It has taken me time to recover from major surgery in order to start my treatment," Middleton, 42, began. "But, most importantly, it has taken us time to explain everything to George, Charlotte and Louis in a way that is appropriate for them, and to reassure them that I am going to be OK."

When Princess Kate fell out of the spotlight, citizens, social media, and celebs alike began to speculate.

Despite public apologies from hosts at 'The View' and Blake Lively, SKIMS founder Kim Kardashian still hasn't budged on her now insensitive post regarding Middleton's hiatus, which was posted nearly two weeks ago.

"On my way to find Kate," Kardashian, 43, captioned a pictures of her standing in front of a car.

"I am stunned and disgusted that this is still here," one user responded.

Cohen on the other hand took advantage of an opportunity to set the record straight.

"I just had to say that right at the beginning," he said. "It's the first opportunity back in front of a live microphone."
