Lindsay Lohan's mother says the U.S. actress is dropping her last name and will be known only as Lindsay, PopEater.com reported.
"Lindsay is dropping the Lohan and just going by Lindsay," Dina Lohan told the celebrity Web site.
"Plus, me and [younger daughter] Ali will be officially changing our last names back to my maiden name, Sullivan."
The PopEater.com report did not say if the Lohans have legally filed for the name changes.
Lindsay, who has been battling addictions to drugs and alcohol for years, is awaiting trial for allegedly stealing a $2,500 necklace. She is on probation for a 2007 driving-under-the-influence conviction.
The 24-year-old actress is best known for her work in "Freaky Friday," "The Parent Trap" and "Mean Girls."
