lindsaynamechange.jpgLindsay Lohan is joining the ranks of Madonna, Cher, Rihanna and other celebs who only go by one moniker -- The actress is planning on dropping "Lohan" from her name and will only be known as Lindsay from now on, according to her mother, Dina Lohan.

"Lindsay is dropping the Lohan and just going by Lindsay," Dina told Popeater. "Plus, me and Ali will be officially changing our last names back to my maiden name, Sullivan."

A source says, "No one in the family want anything to do with Lindsay's father anymore and that includes sharing a last name."

After her parents' divorce, Lindsay had a strained relationship with her father, Michael, but recently mended things following her latest stint in rehab (where Michael often visited her.) But now that Michael's been formally charged with domestic violence and new details about the fight he had with ex Kate Major are emerging (including a disturbing account of how Michael allegedly sliced his wrists and threatened to blame Major for the injuries), Lindsay apparently wants nothing to do with him.

But would dropping the Lohan from her name really give her the fresh start she needs? If Lindsay is convicted for felony theft of a $2,500 necklace by a jury when she goes back to court next month, it may not be enough to change her ailing reputation.
