Mylah Morales used to be Cassie's makeup artist, and she witnessed the aftermath of Diddy beating the "Me & U" singer.

Morales spoke about the assault on Extra TV, explaining that she was with the former couple that day.

"I don't even want to go back to it because it's triggering," she said. "All I [saw] was him walking into the room and saying, 'Where the f*ck is she?' I didn't know what was going on."

Morales then explained how she helped a badly injured Cassie after the horrible beating. 

"I called my friend, a doctor at the time, to treat her because we couldn't bring her to the hospital," she recalled. "We didn't know what the hell to do at that point. Who are we going to call? I'm scared just even talking about this, but I feel like somebody has to ... She was bruised. I mean, badly bruised, like knots on her head, a black eye. All I cared about was to get her to safety. And I took her into my house and kept her there for a few days."

Any reaction to these new details?
