Brad Pitt's recent leg injury is "getting better".

The 48-year-old actor was walking with the aid of a cane as he attended the New York Film Critics Circle Awards with partner Angelina Jolie in New York earlier this month.

He injured the ACL ligament in his knee after he slipped and fell while carrying his three-year-old daughter Vivienne on a ski slope over the holidays.

Brad is healing rapidly following the fall.

"It's better," Brad told E! Online. "I have to wear a brace for a month."

Brad is not worried about his recovery. The actor just hopes that one of his six children with Angelina won't aggravate the injury.

"Then I'll have rehab [after I remove the brace]," he shared. "I'll be alright as long as the kids don't hit me from the side."

Angelina is rumoured to be three months pregnant with the couple's seventh child.

Brad will next appear in crime thriller Cogan's Trade.

Angelina is currently promoting her directorial debut In the Land of Blood and Honey.
