Christina Ricci, who stars as Trixie in “Speed Racer” in theaters on May 9, successfully made the transition from child star to adult star. How? Being a human/alien hybrid may have helped.

Better known as “star children,” the offspring of human and alien mating, these new species were created as a replacement for the human race.

And they look like Christina Ricci.

OK, aliens and star children do not exist, but, if they did, you would be able to find them all over Hollywood.

Ricci is an example of a celebrity who just doesn’t look right. We’ve seen her grow up since “Mermaids,” and we know she has always had a big forehead and a pointy, little chin – like an alien. Put a bad wig on an alien and you would have Ricci as she looked in “That Darn Cat.” The bangs she wears as Trixie doesn’t change that.

Other possible Hollywood star children include Julia Stiles, Reese Witherspoon and both Olsen twins.

Go rent any movie with Julia Stiles in it and watch her forehead. The skull under her forehead seems to move under the skin. It’s freaky! The skin is supposed to move, not the skull! Can you move the bone under your forehead? No, no one can – except Julia Stiles. Verdict: star child.

Reese Witherspoon’s chin is so pointy you can pop a balloon with it. It’s one-third of her face – like an alien. How does the star of “Legally Blonde” go on to win an Oscar? There are some unearthly powers at work there, man. Verdict: star child.

The fact that the Olsen twins are millionaires but have no discernable talents gives them away as “transgenics.” According to www.aliensandchildren.org – research, baby, research – aliens, “Do not understand ingestion of food for energy or need for water (hunger and thirst).” Need more proof? Did you see “New York Minute”? Well, someone did. It made more than $14 million in the U.S. Denial of traumatic events is a characteristic symptom of those who have had alien encounters. Sure, the movie bombed, but someone did see it. More? They were millionaires before they were 10 years old. Now, they are worth $137 million — each. Let’s do the math: $274 million + no talent = alien powers. Verdict: star children.

If these celebrities are not star children, there is a bobblehead doll somewhere in their family trees.

This is no reason you can’t or shouldn’t go out and see “Speed Racer.” It should be great. Just ask yourself why you believe Ricci in a “retro-future” styled movie. “Retro-future”? Aliens.
