At the time of writing, no cause of death has been revealed.

Thea, who had 84,000 subscribers on YouTube, was expecting a child with her partner - a street dancer known as Global Boga.

She announced her pregnancy back in March, when she took to Instagram to write: "We can’t hide this any longer, secrets out.. GOD gave us the biggest blessing yet. 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. Honestly, @global_boga has been the best support EVER and GOD made no mistakes making him the father."
