Miranda Lambert -- Divorce Left Me Thirsty ... I Need A Drink

Miranda Lambert was on the hunt for drinking buddies Friday night in Minnesota ... telling her fans that booze is a good tonic for divorce.

Miranda was performing at WE Fest, when she blurted out, "I wish I've been drinking all day. I deserve it." A short time later she said, "I just got divorced."

We're guessing that wasn't news to concertgoers, who went crazy ... some offering to take a shot with the singer.

Some of her fans say she teared up when she sang "Over You," a song written by Miranda and Blake Shelton about Blake's brother who passed away.
