Thought sure it was this movie she was in...

But it's not. On LMN ads as they quickly flash through various movies - the short haired blond in the bedroom who says "now, look at this..." or close to that wording and then jumps back on the bed laughing and her guy jumps on her. Gosh, want to remember what that movie was and who she is. She played a very likeable slut in the movie.
