LiLo to Leno: Why I Canceled on Barbara Walters

Lindsay Lohan went on the Tonight Show last night to talk to Jay Leno ... days after canceling an interview with Barbara Walters that had been scheduled for 20/20 last Friday. "The timing wasn’t right, right now," a fidgety Lohan explained to Leno when he pointed out that Walters was quite upset over the situation. "I love her, I’m a big fan of Barbara Walters," Lohan continued. "So when it’s right, she knows she'll be the first person I sit down with." Er, make that ... the second person? More from her Leno interview:

• "I guess I could give her one word of advice: Good luck with my dad," Lindsay said of the secret half-sister the world recently learned about.
• "That's great for him," she said of Tim Tebow's virginity, after Leno brought up a tabloid story about the two of them doin' it.
• On why she wanted to play Elizabeth Taylor so badly: "I relate to her, you know, her part of the life that was all in front of the cameras." She says Taylor once sent her a ring and invited her to dinner, but she was too nervous to attend.
• From another recent interview with Us: "I want to be known as an actress, not a troubled starlet," she says. But when it comes to her past, "[I regret] nothing, because then I wouldn't have been able to cry in scenes at the drop of a hat. ... I'm not saying I wanted to go to a jail cell, but I've drawn from all of it."
