Karlie Kloss is heading back to school

Captioning a photograph of her outside the prestigious university, she wrote: "...I haven't been this nervous in years! #firstdayofschool (sic)"

Meanwhile, the 23-year-old beauty recently revealed she would love to go back to education but admitted she was having trouble pinning down exactly what course she wanted to do.

She said: "My ambition is really just to study things that I'm curious about. I want to study computer science. I want to study psychology. I'm fascinated by space. I want to study art history."

And apart from her studies and modelling career, Karlie is also keen on encouraging other women to try their hand at all different types of careers, launching Kode with Karlie, which aims to provide scholarships for young girls to attend summer coding classes.

Of the campaign, she said: "I think it's crucial that young women learn to code as early as possible to ensure that we have a voice and a stake in what the world looks like."
