Actor Brad Pitt says his recent injury to his knee has made him 'lopsided'.

The 'Moneyball' star was forced to walk with a cane for a few weeks after sustaining ligament damage when he slipped whilst carrying his daughter Vivienne, Femalefirst reported.

"I was getting all lopsided. So, I'm trying to balance out now," he said. The couple stepped out together at the Screen Actors' Guild (SAG) Awards at the Shrine Exposition Center in Los Angeles on January 29 and the actor managed to walk down the red carpet without the need of his cane.

Earlier, Pitt, 48, had said his six children - Maddox, 10, Pax, eight, Zahara, seven, Shiloh, five, and Knox and Vivienne, three - with partner Angelina Jolie have been putting him under pressure to propose and he has now promised to buy her a ring.

"We're getting a lot of pressure from the kids. It means something to them. (They asked me to) 'get mommy a ring, so I said 'OK, I will! I will'."
