The `Moneyball` actor was forced to walk with a cane for a few weeks after sustaining ligament damage when he slipped whilst carrying his daughter Vivienne and Brad admits it had made him "lopsided". He told Access Hollywood: "I was getting all lopsided. So, I`m trying to balance out now." Brad`s also revealed 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. He explained on CBS show `Sunday Morning`: "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.`" Although Brad and Angelina had previously vowed not to marry until gay couples are also allowed to, the 48-year-old has recently revealed a change of heart. He said: "We`d actually like to and it seems to mean more and more to our kids. "We made this declaration some time ago that we weren`t going to do it till everyone can. But I don`t think we`ll be able to hold out. It means so much to my kids, and they ask a lot. And it means something to me, too, to make that kind of commitment." Angelina and Brad stepped out together at the Screen Actors` Guild (SAG) Awards at the Shrine Exposition Center in Los Angeles last night (29.01.12). The actor managed to walk down the red carpet without the need of his cane.
