Pretty much ever since she got married earlier this year, there's been speculation that Meghan Markle is with child.

The Duchess of Sussex, 37, has been busy getting to grips with her new life and joining her husband Prince Harry in undertaking royal duties but can't seem to shake the baby rumours. If or when she does fall pregnant, we probably won't know for a couple of months - but there is something we can look out for. Meghan has said in the past that she gets a Brazilian blow-dry, a chemical-heavy treatment, to straighten her naturally curly hair. "My mum is black and my dad is Dutch and Irish, so the texture of my hair is densely curly," she said in 2011. "I’ve been getting Brazilian blowouts for a couple of years." It's something she'd have to give up of she were pregnant, etiquette expert Myka Meier has revealed. "The one thing that might be interesting is her hair," she told Fabulous. “We don’t know what she does to treat her hair now but it is likely she uses a keratin or a Brazilian treatment to straighten it. "As soon as she gets pregnant she will no longer be able to use those same products, which could be very interesting. “I use the same products because I am quarter African and have very curly, frizzy hair and when I got pregnant I had to stop using all of those.”
