Ollie Locke and husband Gareth Locke have announced that they are to become parents following successful IVF treatment in Mexico.
The Made in Chelsea favourites flew out to the country under medical travel exemptions earlier this month and have now revealed that a surrogate mother is carrying their child.
Sharing a video of the fertilisation moment to Instagram, Ollie wrote: "I'm not crying, you're crying!
"This is the very moment our eggs were fertilised... in 9 months time, after being looked after by a very wonderful human we hope to be able to show you what he or she looks like and how much love we have to give!
"I cannot wait to meet you little one and to be your daddy with @garethplocke Xx"
The Locke-Lockes' journey to parenthood has been documented in the current series of the long-running reality show, which ends its run on E4 on Monday night.
