According to TMZ.com, the boxer is seeking treatment for a substance abuse problem and checked into a California-area facility within the past few weeks.
De La Hoya has posted a flurry of introspective tweets in the past few days, including: 'Take a deep breath and let out all that anger that makes you hate. It really is going to be OK.'
He also tweeted: 'Stop finding excuses not to live. Life is controlled by what you make of it and not of what it makes of you.'
De La Hoya retired from boxing in 2009.
