Sofia Vergara is finally speaking out after her heroic moment in Vegas last week -- claiming the woman she rescued simply had too much to drink that night ... and that's why she collapsed.
TMZ broke the story ... Sofia was leaving Hyde nightclub at the Bellagio around 3AM New Year's Day, when she saw the unidentified woman fall unconscious ... and rushed to help her.
Sofia called in to Kidd Kraddick in the Morning yesterday, claiming the woman "was just a little drunk, you know. It was Vegas. It was New Year's."
Sofia says she ran over and called for her cousin -- a doctor -- to come help. Once Sofia and her cousin established the woman was breathing, they waited for paramedics to arrive.
And in case you still don't think she's awesome enough -- here's that picture of Sofia in see-through black tights. Hummana.
