Only weeks after graduating from Oxford University, Malala Yousafzai is celebrating once again – this time, turning 23.

The Pakistani activist for female education and founder of the non-profit Malala Fund celebrated her birthday surrounded by her family and friends in the UK.

Sharing pictures from the celebrations on her Instagram account, Yousafzai joked that she was ready for a “quarter-life crisis”.

“Chapter 23!” she wrote alongside a picture of herself with her mother, Toor Pekai Yousafzai, and father, Ziauddin Yousafzai, who were holding helium birthday balloons. “Thank you for all the birthday wishes,” she added.

She was also pictured celebrating alongside friend and fellow Oxford graduate Vee Kativhu, as well as her brothers and friends.

Priyanka Chopra was among stars to send well wishes to Yousafzai on her birthday, which fell on Sunday – a day officially dubbed as Malala Day by the UN.

"Happy Birthday to such a beautiful soul. Wishing you a year filled with so much love and happiness, Malala", the actress wrote on her Instagram stories, alongside a picture of Yousafzai.

In 2014, Yousafzai became the youngest person to win the Nobel Peace Prize at the age of 17. Three years later, she accepted a place to study at Lady Margaret Hall at Oxford University.

In June, she celebrated her graduation from the prestigious university, completing a degree in Philosophy, Politics and Economics from the University of Oxford, eight years after being shot in the head by the Taliban, in the Swat District of Pakistan, for speaking out about girls' education.

Alongside her studies, Yousafzai has been busy working with the Malala Fund, which helps supports the work of education champions in developing countries and speeds up progress towards girls’ secondary education around the world.
