Former US President Barack Obama, Lady Gaga, LeBron James and K-Pop band BTS are among dozens of celebrities and world leaders who will salute the class of 2020 in virtual US graduation ceremonies replacing the traditional end of high school and college.

In a one-hour multimedia event called “Graduate Together”, to be broadcast on May 16 across multiple TV networks, Obama will deliver a message to high school seniors and reflect on the coronavirus pandemic.

A separate YouTube event called “Dear Class of 2020”, to be hosted by Michelle Obama's Reach Higher initiative and streamed on June 6, the former president will join with the likes of Nobel Peace prize winner Malala Yousafzai, BTS and former Secretary of State Condoleezza Rice in celebrating graduates across the US.
