Actor Brad Pitt is walking with the help of a cane after reportedly tearing a ligament in his knee.
The Ocean's Eleven star was photographed leaving a skin spa in Beverly Hills, California on Thursday (05Jan12) limping as he stepped out with a walking stick.
JustJared.com reports Pitt is using the cane because he has torn his medial collateral ligament (Mcl) - one of four ligaments that stabilises the knee.
A source tells the website, "He tore his Mcl."
