Lindsay Lohan put on a pretty smile and some shiny pants for dinner out at Koi on Friday after the world learned she's once again single. It's a good thing that Riley is out of the picture — he seemed like a dud. I just hope he doesn't do something obnoxious like sell his story about dating the starlet. Ditching Mr. Giles so quickly seems like just another reason why LL doesn't deserve the title of Dumbest Person in Hollywood. More than half of you seem to agree that she's not No. 1 (though she has her place somewhere on the list). Maybe if she keeps up this streak of wise choices, she won't even earn a spot next time around.
