The couple, who found love on the third series of the ITV2 dating show, took to their respective Instagram on Thursday to announce they are expecting a baby boy next year.
Since sharing the joyous news, the former Islander revealed she’s getting practise with early mornings again ahead of their impending arrival as her two-year-old daughter Nora had her up in the early hours of the morning.
Taking to her Instagram Story on Friday, Thurlow, who previously dated Prince Harry, wrote across a photo of her and Nora: “Trying to persuade little Nora that 4.50am really is too early to get up.
“She loves an early start. It's good practise for Christmas morning I suppose.”
Her family update comes hours after she and Jewitt shared a sweet clip featuring their two daughters Nell, three, and Nora learning about becoming big sisters.
In the adorable video, Nell stood infront a blackboard which had “Big sister 101 with brand new module ‘Boys’” written across it along with Thurlow’s due date, May 2024.
Captioning the post, which was set to You Make My Dreams by Hall & Oates, the former bomb disposal expert wrote: “Our lovely girls are getting a baby brother!
“Delighted to share our little family is growing, baby boy due in Spring 2024, it’s going to be a busy house!”
Thurlow, 34, and Jewitt, 33, are one of Love Island's biggest success stories after meeting on the ITV2 dating show and becoming runners up to Amber Davies and Kem Cetinay.
Three years after appearing on the show, the couple welcomed their first child together in October 2020, and got engaged four months later in February 2021.
They tied the knot in September 2021 at Gosfield Hall in Essex, with co-star Marcel Somerville in attendance, and welcomed their second child, Nora, in June 2022.
