Denise Richards, Scarlet Woman

In nature, animals often bear bright colors to warn other creatures of their toxicity.

So it goes among celebrities, such as It’s Complicated star Denise Richards.

Richards was out in midtown Manhattan yesterday, wearing a bright red get-up that screamed, “Come near me, and I will brazenly trash talk you to the media. I will solicit, then reject, your sperm in a very public manner. I have ensured that my own kids need therapy; imagine what I’m capable of doing to yours!”

Thanks for the heads-up, wacky famous lady!

Of course, with your crimson wardrobe, there’s always the danger that your former husband Charlie Sheen will charging at you, snorting like a bull and calling you the N-word.

But that’s a small price to pay for the public welfare.
