"Brad and Angelina," Teigen, who's married to "All of Me" singer John Legend, wrote on Tuesday. "How am I supposed to go to work today?"
Fans were quick to respond to the relatable tweet, writing things like, "Don't divorce John, you guys are love's last hope," "this means you and John are now the No. 1 celebrity couple. Congrats on the power rankings," and "how are ANY of us supposed to go to work?!"
According to court documents obtained by ET, Jolie filed for the dissolution of marriage and listed the separation date as Sept. 15, 2016. The Maleficent star is asking for physical custody of their six children -- Maddox, 15, Shiloh, 10, Pax, 12, Zahara, 11, and twins Vivienne and Knox, 8.
A source close to the couple tells ET that the split "was a long time coming."
"They have been fighting for the last year," the source added. "They haven't slept in the same bed for a big chunk of that. When they were in New York City the last time together, they had separate rooms at the Greenwich and were on their own schedules."
Jolie, 41, and Pitt, 52, tied the knot in August 2014 in France. The two met in 2005 while on the set of their film, Mr. and Mrs. Smith, while Pitt was still married to Jennifer Aniston. Jolie was previously married to Jonny Lee Miller and Billy Bob Thornton.
ET has reached out to both Jolie and Pitt's reps for comment.
