Lindsay Lohan's famous smile doesn't exactly look like a million bucks lately.

On Wednesday, the drama-prone star, 25, hit the red carpet for the THQ launch of the Saints Row: The Third video game in L.A.

When Lohan grinned for the cameras, she revealed yellowed, uneven, somewhat decayed teeth -- presumably the result of her smoking habit, not to mention her much-publicized struggles with drugs and alcohol.

Regardless, the on-probation star sounds like she's attempting to stay healthy. On the same day as the event, she tweeted about her struggles to eat leafy greens.

"Why is kale so hard on the tongue?" she wrote. "It's just not meant to be a 'food friend' of mine, no matter how hard i try! :("

Despite the sad smile, the Mean Girls actress recently stunned during Paris Fashion Week, covering up her assets in a demure dress with a knee-length full skirt. She accessorized with sunglasses, a ladylike Fendi purse and gold pumps. Her long hair was pulled back in a bun and she kept her makeup to a minimum.
