Lindsay Lohan "doing great" in rehab

Lindsay Lohan's mother has insisted that the actress is "doing great" after giving up alcohol.

The Mean Girls star checked into rehab at the Wonderland Centre in Los Angeles last month and mum Dina confirmed that the treatment has been extremely effective.

"She's amazing. She's great and she's happy," Dina explained. "She's in a really good space right now. It's wonderful at Wonderland - how cheesy."
