The 29-year-old royal attended a memorial service honoring the late South African leader and former president at Westminster Abbey in London earlier today.
Harry, who represented Queen Elizabeth II during the service, arrived to the National Service of Thanksgiving event in a formal suit and blue tie. During the memorial, Harry shook hands and met with South African Archbishop Desmond Tutu. Harry also enjoyed a gospel reading by Prime Minister David Cameron and a music and dance performance by a South African troupe.
Also among the service's 2,000 guests was Idris Elba, who recently played Mandela in the movie Mandela: Long Walk to Freedom. Elba arrived at Westminster Abbey in a black-and-white suite before helping to honor the late civil rights legend. Mandela's daughters Zenani Mandela-Dlamini and Zindzi Mandela also attended to celebrate the life of their father.
Mandela died on Dec. 5 at the age of 95. His health had been failing for some time prior to passing away.
He was laid to rest in his childhood village of Qunu on Dec. 15. President Barack Obama, Charlize Theron, Bono and Naomi Campbell were among the celebrities, world leaders and activists in attendance at the burial.
The National Service of Thanksgiving will be broadcast on BBC.
