Laura Dern to Ben Harper: Make Your Mind Up!

Ben Harper has had a change of heart in his divorce with Laura Dern ... TMZ has learned.

Ben still wants the divorce, but he's changed his mind on when he and Laura separated.  TMZ broke the story ... when Ben filed for divorce last month, he listed the date of separation as January 1, 2010.

But last Friday, Ben's lawyer amended his divorce petition, now listing the date of separation as July 1, 2010.  It's unclear why Ben had a change of heart.

As for Laura, it's all a surprise to her.  She didn't know anything about a split until October 8, the day Ben filed for divorce.
