In April, Nicole Thea uploaded a video to YouTube sharing some big, personal news.

She was pregnant with her first child, and she and her partner Global Boga were very excited.

"The first time I felt a kick I cried a bit," she said, with Boga joking throughout the video about his theory it was a boy.

On Instagram she continued to share her happiness, writing "I'm finally creating a beautiful, little human inside of me".

"Can't believe this bubba will be half of me and half of the loml (love of my life)."

In their video announcement, she talked about how Boga wasn't able to join her for scans due to the COVID-19 pandemic and said she hoped restrictions would have eased by the time she was ready to give birth.

The London YouTuber and her unborn child, who she planned to name Reign, passed away on Saturday, July 11.

"To all Nicole's friends and supporters it is with great sadness that I have to inform you that Nicole and her son she and Boga named Reign sadly passed away on Saturday morning," a statement from her family, uploaded to her Instagram account, read.

The family explained that Nicole had "pre-scheduled a few YouTube videos" to upload on her channel before her death, and with Boga's blessing, he "made the decision to allow them to be aired".

"As a family we ask that you give us privacy because our hearts are truly broken and we are struggling to cope with what has happened."

Thea's mum said she would missing her "beautiful baby girl Nicnac and my grandson Reign" for the rest of her life.

At this stage, the circumstances of Thea's death remain unknown.

Her most recent video, uploaded about an hour before the Instagram announcement, was pre-scheduled and followed Thea's experience with a milk bath. It also showed moments from her maternity photo shoot.

Thea, who had almost 100,000 subscribers on YouTube and 200,000 Instagram followers, built up a loyal following through years of dancing, makeup and fashion videos, before announcing she and Boga were expecting in April and sharing lots of pregnancy content
