Sophia Grace is having a baby girl

In the YouTube clip, which showed her popping a pink confetti cannon and a cake with a pink sponge, she said: "A lot of people do their gender reveals on their YouTube channel.

"I personally don't mind doing it privately, with my very close family, because that is just the sort of thing that I like to do."

Sophia - who is already a mother to 18-month-old son River - has known the gender of her unborn child for a while now and is struggling to settle on a name.

She admitted: "I'm not one of them people that has a list of names in their notes.

"Like, I know loads of girls-even ones who aren't pregnant-have their baby names ready, and I am just not that girl.

"I haven't found one that I really love yet, so I'll have to have a good think about it."

Sophia - who has not disclosed the identity of the father of her children - wanted to hold off unveiling the sex of the unborn tot and waited until she was 20 weeks pregnant to share her pregnancy.

In a video on her channel uploaded last month, she said: "I'm so excited to be doing this video. I've been hiding this for a super long time. I'm a very paranoid and anxious person. I always like to wait until I'm around the 20-week mark. I've had both of my scans and everything's been fine so far, which is really good."

Sophia is excited that her eldest will have a sibling who is so "close in age" to them and she is looking forward to watching them grow up together.

She said: "It's going to be so nice for him to have a younger sibling. And because they're quite close in age, they can grow up together, and I just think that's really sweet."

The former child star previously explained that she has kept her partner's identity out of the public eye because she wants to keep something to herself.

She told E! News: "Because I have always been in the spotlight, I feel like I want something just to keep to myself. Just something that I can keep private and that I can just enjoy myself and not have to share it with everyone."
