Former couple attend the same event
The pair, who divorced in 2005 after five years of marriage, took part in the Hope For Haiti Now telethon in LA organised by George Clooney.
Brad, 45, introduced one of the artists on stage while Jennifer, 40, helped answer calls on the donation hotline.
Brad’s partner Angelina Jolie, 34, is not thought to have been at the event.
Meanwhile, Cameron Diaz, 37, was snapped having a chat backstage with her ex Justin Timberlake, 28.
At one point, the actress was even photographed touching the singer’s chest.
Justin, who split from Cameron in 2007, is now dating Jessica Biel, 27.
