And Morgan responded back to the outspoken Sports Illustrated model.
Not one to shy away from a Twitter debate, the new mother fired back.
Morgan then professed his love for Teigen’s husband John Legend, 37, while taking another stab at the model.
And Teigen had a rapid response.
The saga continued to go back and forth on the social media platform, as Morgan wrote that Legend had “problems” since he decided to marry Teigen, before threatening to pen his next article about her next after the model blocked his account.
This is not the first time Teigen and Morgan have been involved in a heated Twitter feud, with the model ousting Morgan over one of his tweets following the June death of Muhammed Ali, which she believed to be racially charged.
It comes after Aniston penned a powerful essay to the Huffington Post titled “For The Record,” in response to media speculation she was pregnant.
"For the record, I am not pregnant. What I am is fed up," the actress wrote, adding women "are complete with or without a mate, with or without a child. We get to decide for ourselves what is beautiful when it comes to our bodies."
Teigen is not the only celebrity to show their support for Aniston, with male and female stars voicing their opinions, including her husband Justin Theroux who called her his “#WomanCrushWednesday."
