Dina has come under scrutiny following claims from her ex-husband, and Lindsay's father, Michael Lohan. The reformed drug addict wants Dina to undergo drug testing herself.

"I do not believe Dina should be drinking in front of our daughter," he says. "If she continues to do this, I guarantee Lindsay will fall apart again."

He continues, "Back when Dina and I met, everyone was partying and using cocaine ... I now work as a drug counsellor with teenagers [and] am willing to be tested by the court all day, every day of the week. I know I will come up clean. But when my lawyers sat with Dina's lawyers ... she was reluctant to be tested."
