JASON ALDEAN has found the woman of his dreams . . . again. He got engaged to "American Idol" contestant BRITTANY KERR on Wednesday, two years after they were caught messing around while he was married.

He popped the question during a visit to the San Diego Zoo.  Brittany posted a photo of herself feeding a sea lion to Instagram.  She captioned it, quote, "My man did it again.  Today was amazing."

It'll be her first marriage and his second.  He's 37, she's 26.  There's no word on a wedding date.

We saw Brittany backstage at Jason's show at SPAC, she was fun, perky and bubbly - Jason looked happy and in love.

Although scandalous, they do look happy, and hopefully they both have finally found their soul mates!
