The Duchess of Cambridge has visited the Olympic Park in London as part of her work as patron of the charity SportsAid.
Kate left Prince George at home with Wills and flew solo at the engagement which saw her play volleyball with young athletes at the Queen Elizabeth Olympic Park in East London.
The Duchess showed off her ball skills (despite her towering wedges) and spoke to athletes and volunteers at the park.
Her sporting engagement comes just days before George will be christened in the Chapel Royal at St James's Palace on Wednesday.
Royal aides said Kate was keen to meet the athletes that SportsAid was helping face-to-face to get a 'detailed insight into the challenges they face'.
The charity was set up in 1796 and funded two-thirds of the British team at the London 2012 Olympic and Paralympics, where Kate made several appearances – before her pregnancy was announced.
