The trouble seems to have started when Teigen called out Trump for gloating about a meeting with black pastors to which the press was not invited.

"Will be meeting on Monday at Trump Tower with a large group of African American Pastors. Many I know — wonderful people! Not a press event," wrote Trump on Sunday.

Teigen smartly recognized Trump's hypocrisy at announcing this so-called under-the-radar meeting to only his five million followers and replied, "So don't tweet about it you twat."

Trump's supporters quickly began attacking Teigen, who already had quite a week defending her stance on Planned Parenthood, and when Trump retweeted a fan's super-rude message to her, she had a hilarious — and accurate — response.

Despite abruptly canceling the meeting, Trump held it after all, and used his favorite adjective to describe it afterwards.

"I thought it was an amazing meeting," he told media gathered outside. "I met some fantastic people, some of whom I've known. You know, it lasted for more than two and a half hours. We came up with lots of good ideas and lots of future ideas. But I thought it was an amazing meeting."

Teigen and husband John Legend are currently expecting their first child, thought to be due in April or May, although they have yet to officially announce a due date.
