"What's going to be diffent this time?" Oprah asks as a follow up. The teaser does not include any response from Lohan.
Some other hard-hitting questions from the teaser include:
"When you get the first DUI — is that a wake-up call?" and "What do you know about yourself now, that you wish you'd known six rehabs ago?"
