This time troubled actress Lindsay Lohan, 26, is in the public eye through no fault of her own, but a scandal that concerns her equally-troubled family. Turns out LiLo has a younger half sister, Ashley Kaufmann, 17, whom she allegedly didn't know about until she was asked about her on Good Morning America while promoting her new highly anticipated Lifetime flick, Liz & Dick, in which she plays screen legend Elizabeth Taylor.

"I didn't even hear that, so thanks. I don't read the news. I don't pay attention to that," Lohan said about the news that has been rumored since 2008 and was recently confirmed when Lohan's daddy dearest, Michael Lohan, went on The Trisha Goddard Show to have a paternity test, in which it was revealed that he was the biological father of Kaufmann. Yes, that also means he cheated on Dina Lohan with the young girl's mother.

"I don't want to be a part of what they've called the Lohan train wreck," Kaufmann told the audience on the show before the DNA results were announced. After all was said and done and Michael moved to embrace his new teenage daughter, she backed up. "This is the first time I've met you," she said. "I'm sorry but I'm not sure."

For Lohan's part, she's taking it all in stride and focusing on her portrayal of Taylor. "I hope that my love for acting shows through," she said about her upcoming performance. "I hope they enjoy the portrayal. I did the best that I could, and I hope Elizabeth is happy, watching from above."

Lohan also talked fondly about the family members she did know about. "My sister and brother and mom watched it, and to have people I love enjoy it and appreciate it makes it so much more worth it."

And Lohan is looking for more "worth it" moments in her upcoming movie roles. "I'm reading scripts every day. I keep calling my agents to say, 'Keep me on set!' It's safer that way," she joked.
