If you've been on Twitter today, you may have seen #GirlsinSTEM trending all over the place, thanks to a conference currently taking place all over the UK.
For those who don't know, STEM refers to school/college/uni subjects in science, technology, engineering and maths - subjects which have traditionally had a much lower rate of female students in comparison to male.
But with STEM subjects leading women to securing some of the best jobs with the highest wages, motivating girls to keep on with things like maths and science after high school is key to eliminating the gender pay gap.
There tends to be a bit of negative stereotyping around girls who take what could be perceived as 'geeky' subjects - but it's time for that to staaaaahp.
Here's a load of female celebs who took STEM subjects, for example, some of whom might surprise you:
Natalie studied science at school, with drama and dance studies on the side, before earning a psychology degree from Harvard University. Amazing. She even skipped the world premiere of her film Star Wars Episode 1: The Phantom Menace so she could study for her high school final.
Cindy kept on with science at school, and was so smart she was given a full scholarship to study chemical engineering at Northwestern University. She eventually took up modelling instead.
Teri studied mathematics and engineering at De Anza College - and her love of STEM is in her genes. Her mother excels in computer programming, while her dad is a nuclear physicist.
The Golden globe winning actress graduated from the University of Melbourne in 2004 with a Bachelor of Arts Degree in Economics and Fine Arts.
TV presenter Rachel is an academic who studied Mathematics at Oxford University after gaining 4 A's at A Level. She also helps increase the awareness and excitement around maths by being the ambassador for World Maths Day.
Studied BSc biology at Vassar College, New York. Having studied biology at university, she went on to undertake research with her father, Dr Lee Kudrow, a world-renowned headache specialist.
Studied BSc and PhD neuroscience at University of California, she's best known for her role as Dr Amy Farrah Fowler in The Big Bang Theory. Like her character, she is a certified scientist. With a degree in neuroscience, she completed a PhD on obsessive compulsive disorder in those with the genetic disorder Prader-Willi syndrome, in 2007.
So there you have it, your options are endless and don't let anyone tell you otherwise. The good news is that girls taking STEM subjects IS on the rise.
Education Secretary and Women and Equalities Minister Nicky Morgan says: "Since 2010, we have seen 12,000 more girls entering STEM A levels and there continues to be more girls studying these subjects than ever before, showing no subject is off limits because of your gender."
