The '7 Days' singer said that he was "honoured" to be asked to perform at the event at the Millennium Stadium, Cardiff on October 8.
The concert plans were announced last month by the late singer's mother Katherine and siblings LaToya, Tito, Marlon and Jackie.
David wrote on his Facebook page: "I am honoured to announce I will be performing alongside some of the world's greatest artists at the Michael Jackson tribute concert."
The concert has been branded as "inappropriate" by Randy and Jermaine Jackson as it clashes with criminal proceedings against the late star's doctor Conrad Murray.
Ticket registration for the concert was supposed to commence on Thursday, but has now been put on hold.
Chris Hunt from Global Live Events told the Western Mail: "We will be announcing an incredible lineup very soon. The registration period was put on hold because we want people to know who they are registering to see."
JLS have expressed their hopes of performing at the concert.
