Oscar De La Hoya -- In Rehab

We're told De La Hoya is seeking treatment for a substance abuse problem and checked into a California-area facility within the last few weeks.

De La Hoya has posted a flurry of very introspective tweets in the past few days, including, "Take a deep breathe and let out all that anger that makes you hate. it really is going to be o.k." and "Stop finding excuses not to live. life is controlled by what you make of it and not of what it makes of you."
