Not myself tonight ... clearly.

Freddy Krueger Good Genes or Good Docs?

Freddy Krueger has got killer looks.

Here's the disfigured razor-sharp character back when he starred in the original 1984 film "A Nightmare on Elm Street" (left) -- and 26 years later, the 2010 version in the new remake (right).

He's dreamy.

Julia Roberts Blind Sided By Bullock ... Again

Sandra Bullock's divorce and baby news has covered up Julia Roberts ... literally.

While Sandra and her new baby Louis landed the cover of People's "World's Most Beautiful People" issue, Julia -- who got the top beauty honors and should have been the cover girl -- is relegated to a blip on the upper right hand corner of the mag.

This on top of the fact that Sandra won her Oscar for the box office hit "The Blind Side," a role Julia originally turned down, proves sometimes being a "Pretty Woman" just isn't enough.

Hollywood's Beachin' Blondes!

The only thing hotter than a teeny-weeny bikini this summer is one of these smokin' blonde babes.

He's golden.

Britney Spears -- Free to Go Free Boobin'

Despite multiple reports to the contrary ... Britney Spears' father has not given her a bra ultimatum -- in fact, we're told he laughed when he heard the story.

As the tale goes, Jamie Spears was embarrassed by pics of Brit Brit showing off her nip nips, so he imposed a "must wear a bra" rule on his famous conservatee. But sources close to the family tell us there is no such rule in place, nor has there even been any thought of one.

We're told Jamie's feeling is this ... you can't make any 28-year-old woman wear a bra if she doesn't want to ... especially Britney.

Control her finances? Yes. Her undergarments? No.

Carrie vs. Taylor Who'd You Rather?

Blonde country darlings Carrie Underwood, 27, and Taylor Swift, 20, both appeared at the same concert in Vegas on Monday.

Question is ...

Nobody said life is fair.
