She wrecked her car in Beverly Hills in May, and two months later was involved in a car chase. In both cases, she possessed a small amount of cocaine. By August, Lohan was in treatment at a rehab facility in Utah. In recent months she has mostly stayed out of Hollywood's limelight.

Dina Lohan came under criticism for, perhaps, allowing her daughter to live a late-night life of Hollywood club-hopping, and E! acknowledged she has faced "intense scrutiny"

But Lisa Berger, executive vice president of original programming for E!, said Dina Lohan "is an incredibly hard-working, passionate mom that I think our viewers will find both relatable and highly entertaining."

E! said it had been given unprecedented access to the Lohan family.

Ali, whose real name is Aliana, also began modeling as a child and has some limited acting experience appearing in small roles in movies such as "The Parent Trap." There are also two Lohan bothers -- Cody, 11, and Michael, 20.
