Troubled actor Lindsay Lohan is planning to drop her surname and wants to be known by her first name only now. “So many of the greatest people in showbiz are known by just their first name. Look at Oprah and Beyonce. Now you can add Lindsay to that list. And it’s a way for them all to start over. No one in the family wants anything to do with Lindsay’s father anymore, including sharing his last name,” said a source.
