MSNBC co-hosts Joe Scarborough and Mika Brzezinski from "Morning Joe" are engaged to be married — but not all seems well in their relationship.

The exchange left some critics wondering: if things are uncomfortable on-camera, how bad are they in private?

Thursday, things got embarrassing when Brzezinski went on an unhinged tirade against President Donald Trump, calling him "narcissistic" and "mentally ill".

"I said it months ago, and now everyone is starting to say it like it's new, and it's OK to say. He's not well! At the very least, he's not well," Brzezinski said. "And he's so narcissistic, he does not believe the rules apply to him, and that's where the ignorance label may apply because this is a man who says he can grab women anywhere because he's famous."

The rest of the panelists — including her fiance Scarborough — began to grow uncomfortable and started having side discussions.

"Stop right there," Scarborough said during Brzezinski's diatribe. "I need an eject button."

Brzezinski demanded to know why no one was paying her any attention hate-filled rant.

"Nothing I have said is crazy!" she insisted, when Scarborough told her, "We'll talk about it in the break."

After, Scarborough warned Brzezinski to keep herself within "the guard rails" of reason.

"Joe," she snapped back. "I am keeping it in the guard rails!"

Later, when Brzezinski launched into a fresh rant, all of the panelists — including Scarborough — began muttering and laughing at her.

"No, we're not talking [about you]" Scarborough insisted. "We're not talking. … OK, that's fine, that's fine."
