Fabolous turned himself in on Wednesday night after allegedly assaulting the mother of his children, Emily B. He was booked for 2 felonies ... aggravated assault and making a terroristic threat.
Emily first contacted police, telling them Fabolous had hit her.
The rapper was accompanied by his attorney when he went to the police precinct. He did not spend time in jail ... instead, he was cited for the alleged incident and given a ticket for his court appearance.
Late Wednesday night, he seemed to be reacting to his arrest with a post about his heart breaking. Emily and Fab have 2 children together, ages 2 and 10.
