Here’s one way of celebrating fatherhood. Matthew McConaughey has raised eyebrows in Nicaragua after the actor, who is expecting his first child with girlfriend Camila Alves later this Summer, was snapped dry-humping and trying to get his freak on with random strangers at a beach bar last week.

“He was acting like an out-of-control 18-year-old,” says a Star Magazine spywitness who was on-hand for Matt’s soiree at the Iguana Bar in San Juan Del Sur on June 6th. “He already seemed to be drunk when he arrived alone, and he only got worse from there on. He was putting the make on every woman in his path, throwing his arms around them and trying to kiss them, and trying to dirty-dance with a few out on the floor. But he was a mess, slurring his words and stumbling around.”

“A few minutes after he finally left the bar, someone found him searching through a sewage ditch outside. When they asked him what he was doing, he mumbled, ‘I’ve lost my flip-flops!’”
