"Baby number 4 incoming!"

Vogue and Spencer already share three children: Gigi, Theo, and Otto.

Vogue has previously opened up about the possibility of having a fourth child with Spencer, including in 2024 when she revealed the couple didn’t see eye to eye on whether to expand their family again.

However, it seems those earlier disagreements have since eased, with the couple now appearing to be on the same page.

Vogue shared three sweet snaps of her and Spencer, as well as their three children, on a beach in St Bart’s to announce the happy news.

Vogue showed off her baby bump as she playfully tapped Spencer’s abs, alongside a sweet snap of the pair posing with their three children, before Spencer rounded things off with the classic hands-on-the-bump pose favoured by expectant dads.

"BABY NUMBER 4 INCOMING…" Vogue captioned the post.

Fans and celebrity friends were quick to flood the comment section, congratulating the couple.

Roz Purcell wrote: "Congratulations," while Nadia Forde added: "Gorgeous gorgeous gorgeous."

Previously speaking about the possibility of having a fourth child, Vogue admitted she was slightly more hesitant about the idea than Spencer.

"I had a timer on myself thinking: 'I’ll decide at the end of this summer', and now it’s the end of summer and I still really just don’t know," Vogue told the Sun at the time.

"If I said: 'Let’s go with it', Spencer would do it straight away, but I think of the logistics, whereas he doesn’t.

"And he doesn’t have to carry a baby for nine months, so it’s a bit more of a decision for me."
