Brad Pitt and Angelina Jolie resumed their usual PDA Thursday night at a charity ball.

The two -- who recently battled split rumors -- didn't leave each other's side as they mingled with celebs including George Clooney and Matt Damon and wife Luciana at the UNICEF Ball in Beverly Hills.

Throughout the night, Jolie, 34, gazed at bearded Pitt, who turns 46 next Friday.

The two lit up when they got to meet former boxing champ Muhammad Ali, 67, who suffers from Parkinson's Syndrome.

As Jolie chatted him up, she kept running her fingers through Pitt's hair.

Before she left Ali's side, she gave him a very warm hug as Pitt looked on.

On Thursday, in an op-ed piece for Newsweek, Jolie criticized President Barack Obama for not working harder to improve "the lives of the people of Darfur."
