Serena Williams - 23-time singles grand slam champion - has shown her charitable side by helping to build a school in Jamaica.

The 38-year-old donned a hardhat, work-boots and a pair of jeans as she took a hands-on approach in the construction of Salt March Elementary School in Trelawny Parish, Jamaica alongside non-profit charity, Helping Hands.

Other celebrities assisting with the mission were singer, Sean Paul and ex-tennis player turned Rogers Cup director, Karl Hal 

Through her charity, the Serena Williams fund and their "Serena Ventures" campaign, the mother-of-one has also built schools in Kenya, Uganda and Zimbabwe in conjunction with Build Africa. The aim is to boost the bottom line at individual companies.

In a statement on her organisation's site she said: "In 2014, I launched Serena Ventures with the mission of giving opportunities to founders across an array of industries." 

Serena Ventures invests in companies that embrace diverse leadership, individual empowerment, creativity, and opportunity.

As we grow we hope to mentor young founders and take burgeoning entrepreneurs to the next level," she said.

The Serena Williams Fund was originally established to promote equality throughout business, where it be based on race, gender, disability or any other barrier to success in business.
