"I felt she was honest. She was authentic," Winfrey said during an appearance on Monday's CBS This Morning.
She added, "She looked good. She looked strong. She looked healthy."
What's more, Winfrey noted that Lohan, who has a history of being tardy, not only arrived for the interview on time, "she was earlier than I was. She was 20 minutes early."
And clearly, Winfrey is in the 27-year-olds' corner.
"I said to her, 'I want you to win.'"
Meanwhile, over on Today, Winfrey was asked about the Travyon Martin case, giving some of her first public remarks regarding George Zimmerman being acquitted of all charges in the shooting death of the 17-year-old.
"It's so easy during this time -- Trayvon Martin, Trayvon Martin parallel to Emmett Till, let me just tell you. In my mind, same thing," she said. "But you can get stuck in that and not allow yourself to move forward and to see how far we've come."
