If you're feeling a bit crummy today - your hair is doing that weird flick thing no straightener can tame, your stomach is bloated, and you feel a cold sore coming on, we think you're in need of a bit of model Iskra Lawrence's words of wisdom.

Her thoughts on body shaming will make you feel tip top again.

Earlier this month, the body positivity campaigner released a video titled 'Blaming Your Body' as part of her self-care Sundays Youtube series, and took the opportunity to address society's tendency to blame their bodies for their failed relationships, jobs and lack of confidence.

In the video, the 26-year-old beauty – who earlier this year opened up exclusively to ELLE UK about the importance of giving up on perfection – explains what exactly she means when she refers to 'body blame'.

'We go through life and quite often like to make excuses. There's nothing wrong with that, it's a very normal thing, but one way we do that is [by] blaming our outward appearance,' she says.

The British beauty explains we often do this in cases, for example, when we fail to receive a call back from a date and subsequently blame our weight, or believe we didn't get a job because the other candidate was more beautiful or skinnier.

'There are ways we blame our body and allow our bodies from holding us back from doing so many things.

'How many people do you know that are so uncomfortable putting on a bathing suit they miss out on opportunities in life?

We can't keep blaming our bodies and letting our insecurities hold us back from living life,' she tells her viewers.

The model – who first hit the headlines when she posted two side-by-side pictures that showed the thigh gap to be a myth, last year, and recently opened up on how to love your body – urged her fans to put a stop to body blaming and, instead, instil confidence in their friends when they hear the hint of self-deprecation or negativity towards their bodies.

'The next time you see yourself in a situation and go straight to the excuse 'I can't wear that dress because I have rolls'...do you want to wear that dress? Because if you want to wear that dress and it's a gorgeous gown and you think you're going to shine in it and look confident and rock it, you need to wear that dress.

Based in New York and having walked in several New York Fashion Week shows earlier this year, Lawrence went onto emphasise the importance of finding a partner who won't judge when you gain or break out into spots.

'If you find someone who will accept your insecurities, that's a pretty amazing person.

'Life is happening right now, don't let it run away from you. Stop blaming your body, it's your home, it's a magical place and a vessel.

'We have control of how we feel,' she adds.

You heard the woman, stop blaming your body and start loving it.
