The former Love Island contestant revealed she gave birth to a baby girl named Sahara Jean Stacey on October 30 at 12.09pm.
The 30-year-old shared the news on Instagram alongside photos of the couple in hospital with their newborn.
“Sahara Jean Stacey. Born 12.09 on the 30th October 2025,” the post read.
“We are more in love than we ever could have imagined. Thank you so much for all of your messages we’re so grateful. Time to enter the baby bubble.”
Fellow Love Island stars including Tasha Ghouri, Amber Davies, Demi Jones and Chloe Burrows were among those congratulating the couple in the comments.
Harrison, who rose to fame on The Only Way Is Essex before appearing on Love Island in 2017, has become a prominent campaigner against image-based sexual abuse and deepfakes.
Her activism followed the conviction of her ex-partner, Celebrity Big Brother winner Stephen Bear, who was jailed in 2023 for voyeurism and sharing a private film of them having sex without her consent.
Harrison waived her right to anonymity and has since spoken to MPs on the Women and Equalities Committee and at the Labour Party conference about her experience.
She fronted the ITV documentary Revenge Porn: Georgia Vs Bear and earlier this year released Georgia Harrison: Porn, Power, Profit, which examines deepfakes and image-based sexual abuse.
Bear was jailed for 21 months but walked out of prison in January after serving 10-and-a-half months.
Harrison has also appeared on Love Island: All Stars and won Channel 4’s Celebrity SAS: Who Dares Wins with boxer Lani Daniels.
In October, she was made a Member of the Order of the British Empire (MBE) for services to tackling online privacy and cybercrime awareness at an investiture ceremony at Windsor Castle.
