delahoya_X17230picWM.jpgOscar De La Hoya is holding back NOTHING in a candid new interview with Spanish-language network Univision. He's admitting to past drug and alcohol abuse ... and infidelity. Back in 2007, X17online exclusively obtained photos of De La Hoya dressed in women's underwear and stockings taken by a stripper, not his wife Millie Corretjer.

The 34-year-old boxer, who married Corretjer on Oct. 5, 2001, admits to being unfaithful. He adds, "We are obviously not talking a Tiger Woods here, but I was unfaithful."

De La Hoya, who retired from boxing back in 2009, says he has been sober for three months. The championship fighter reveals:

    "Rock bottom was recently. Within a couple of years, just thinking if my life was even worth it. I don't have the strength; I don't have the courage to take my own life. But I was thinking about it.''

As for which drugs he abused, the boxer also admits:

    "My drug of choice was cocaine and alcohol, hmm. Cocaine was recent, the last two years, last 2-1/2 years, and I depended more in the alcohol than the cocaine."
