Britney Spears and Sam Asghari reveal 'devastating' news about loss of 'miracle baby'

American singer-songwriter Britney Spears has revealed the "devastating" news that she has experienced a miscarriage. 

The musician took to Instagram on Sunday (NZ time) to reveal she and her fiancé, Sam Asghari, had lost their "miracle baby". 

"It is with our deepest sadness we have to announce that we have lost our miracle baby early in the pregnancy," the couple’s post said.

"This is a devastating time for any parent. Perhaps we should have waited to announce until we were further along, however, we were overly excited to shared the good news.

"Our love for each other is our strength. We will continue trying to expand our beautiful family. We are grateful for all of your support. We kindly ask for privacy during this difficult moment."

It comes just over a month after Spears announced she was pregnant and carrying her first child with Asghari.

"I lost so much weight to go on my Maui trip only to gain it back. I thought 'Geez, what happened to my stomach?' My husband said: 'No you're food pregnant silly!' So I got a pregnancy test, and well, I am having a baby," Spears announced via her Instagram.

Spears and Asghari announced their engagement on Instagram in September 2021.
