"We did what we had to do to protect her,” Dina tells. “We did that for court purposes and the warrant purposes. To clear all that up before she hits American soil, which we have done, so she is now able to come."

Talking to Radar Online, Mama Lohan added, “There was no music to face. We were dealing with issues to get her back safely -- without an arrest and vacate the warrant. And that takes time, that doesn’t happen overnight. There are a lot of phone calls, a lot of people involved and a lot of decisions being made. So we did what we had to do to protect her.”

Finishing up, Dina says that Lindsay “is committed, is serious; she will be there and she will make up the classes, we’re obviously going to do that the minute she lands."
