Reality TV star Ferne McCann has announced the birth of her daughter through her Instagram page.
The presenter and former The Only Way Is Essex star, 27, said the baby girl came a week early.
The father of the child, 25-year-old Arthur Collins, is on trial accused of carrying out an acid attack at the Mangle E8 nightclub in Dalston, east London, in April.
McCann and her ex-boyfriend were out celebrating the news of her pregnancy when the corrosive substance was thrown during a row in the crowded club, Wood Green Crown Court heard.
Announcing the birth, McCann wrote: "Welcome to the world my darling. Didn't expect to see you a week early.
"I'm so in love & bursting with pride. It's a girl."
Collins, of Broxbourne, Hertfordshire, admits throwing the substance but insists he did so having snatched it from another man's hand who he thought was going to spike someone's drink with it.
He denies five counts of grievous bodily harm with intent, and nine counts of actual bodily harm against 14 people.
Andre Phoenix, 21, of Tottenham, north London, is also on trial over the alleged attack. He denies four counts of GBH and two counts of ABH.
The trial resumes on Monday.
