Sophia Grace gives birth to a baby boy

Sophia Grace has given birth to a baby boy.

The 19-year-old star - who shot to fame on The Ellen DeGeneres Show at the age of eight alongside her younger cousin Rosie McClelland, when the TV host spotted them singing Nicki Minaj's hit Super Bass on YouTube and invited them to become regular cast members - welcomed her first child with her mystery boyfriend over the weekend and took to social media on Sunday (March 5) to announce that she had given birth a week earlier.

Without revealing the name of the little one, Sophia posted a black-and-white image of the tiny hand clutching her finger and captioned the post: "Feb 26 [white heart emoji]" (sic).

Rosie was quick to comment on the picture and as she wrote: "I love him so much already [blue heart emoji]."

Sophia recently admitted she "couldn't face" telling her dad she was pregnant and asked her mom to break the news.

She said: "The first person that actually knew was my mom. My mom's reaction obviously, at the start, she was a little bit like, 'Oh wow.' But she just got used to it straight away and she was always really happy and excited about it. Just in any normal family, it's sort of a hard thing to tell your dad-when you're a girl-that you're pregnant, and I'm sure people understand it can be a little bit awkward.

"We were trying to think of a way to tell my dad and, eventually, I just got my mom to tell him because I couldn't face doing it myself."

The Youtuber went on to explain that she initially thought her dad might feel concerned over her young age but insisted that she feels "ready" to become a mother.

She added: "I thought he might be like, 'Maybe you're a bit young,' or something because I am quite young. It's not really about age. It's just depending on whether you feel ready or not-and I think I definitely feel ready."
