Just days after Culpo emerged victorious at the Miss Universe competition last month, photos of the beauty queen taking shots of hard liquor surfaced on the web -- a problem since she's not exactly 21.
We reached out to Culpo -- who told us, "Like many college students I was curious and did experiment with alcohol in college."
She adds, "I would be lying if I told you I did not experience what many students do during their college years. I take responsibility for my actions."
Culpo says the pics were taken during her freshman year at Boston University -- but notes she hasn't had one drink since she won the title of Miss USA back in June.
It's too bad Culpo's parents weren't with her during the boozing sessions -- 'cause Massachusetts is one of the states where it's OK for someone under 21 to booze in a bar as long as that person is with a parent who consents.
