LindsEllen200.jpgLOS ANGELES, California (X17online) - Lindsay Lohan was apparently caught off guard by the sudden end of her relationship with Samantha Ronson.

"I had no idea what was going on. I just hadn't seen her in, like, a week. She, like, disappeared," Lohan reveals on Thursday's Ellen DeGeneres Show.

So what was behind the split - the "Mean Girls" actress isn't sure, or she isn't saying, but she said it wasn't because of any cheating.

She's also doesn't have any idea why Sam's family would try to get a restraining order against her.

"I've never done anything for people to assume I'm dangerous," an exasperated Lohan said.

Now, Lindsay says, it's time for her to focus on her career. "When people are together so much it gets really difficult, and you forget who you are because you're more concerned about being with the other person. I think it's been really good for me. I thought it would be so much harder, and it hasn't been. My sister’s been here with me."
