Diddy's baby mama Dana Tran made a surprise appearance on the first day of his sex trafficking trial.

Tran, who has a two-year-old daughter with the disgraced rapper named Love Sean, strolled into the Southern District of New York Federal Court on Monday.

The cybersecurity director arrived in an all-black outfit of a frilly blouse, pants, high heels and sunglasses and carried a matching Chanel purse.

Sean 'Diddy' Combs is on trial accused of abusing, threatening, and coercing women for years, including at 'freak off' orgy afterparties to his famed celebrity-filled events.

He faces life in prison on five federal charges: racketeering conspiracy, two counts of sex trafficking and two counts of transporting individuals for prostitution.
