Derek Fisher -- Files for Divorce

NY Knicks coach Derek Fisher has filed for divorce from his wife Candace ... just one month after they celebrated their 10 year anniversary. Fisher filed the divorce docs in Los Angeles -- citing irreconcilable differences as the reason for the split. The couple has two children together, twins ... including a daughter who suffered from a rare form of eye cancer. Fisher was famously let out of his contract with the Utah Jazz back in 2007 so he could spend more time with her and help her with treatment.
