Cassie Ventura, the former girlfriend of Sean “Diddy” Combs and one of his accusers, could take the stand as early as Monday as one of the first three witnesses called in the government’s sex-trafficking case against the music mogul.

She is expected to be the third witness. The first witness set to testify is a male escort, and a second witness hasn’t yet been identified. Footage of Ventura being allegedly assaulted by Combs has been allowed by the judge for jurors to watch.

The “Me & U” singer was seen cradling her growing baby bump while waiting outside of a friend’s brownstone apartment building in Manhattan Wednesday.
