Mario Falcone became the father for the first time.
Former TOWIE star and his fiancé Becky Miesner welcomed a son on Friday night, named Parker Jax.
Mario announced the news announcing the picture of his hand of a newborn who rested on their own.
She said, "Happy to announce the birth of our lovely boy PARKER JAX FALCONE, weighing 7 kg 4oz."
"And mum @ beckymiesner1 and baby are fine. Absolutely perfect!"
Mario and Becky decided to postpone their wedding by 2019 earlier this year, after Becky found out she was pregnant.
Mario said OK! magazine, "We were supposed to get married in August. Now we've been redirecting for the next spring.
He added: "We want three or four children, so we hope we'll end up with a boy and a girl."
