BuzzFoto – We had a source that called this one in recently after being at a resort with this singer (who has done a little acting here and there.) Apparently, our source saw the celeb at an all-inclusive resort and claims that the girl was pounding the alcohol down as fast as she could the entire time. She was constantly wasted, wore no underwear under her tiny sundress, and let strangers hit on her and grope her constantly. Classy! She allegedly never had a moment where there wasn’t a drink in her hand. Except for the time our source saw her giving an older mystery gentleman what we’ll call, um, ‘lip service’ in a public dining area. But you don’t really need two hands for that. Not Jessica Simpson.
