Kendall Jenner I'm 18 ... So Here are My Nipples

After only 16 days since her 18th birthday … Kendall Jenner decided to give the world a glimpse of her nipples … leaving everyone wondering ... what took so long?

Who'd you rather?

Kendall posted the pic on Instagram today ... she's wearing a sheer black top … leaving no doubt she's now officially in the Kardashian game of selling sex.

Now here's the question ... does it all end with nipples, or will Kendall walk the path forged by her older sister, with the helping **** of Ray J?

And while we're at it ... we gotta ask ...

Pierce Brosnan GOOD GENES OR GOOD DOCS?

Pierce Brosnan's looks cannot be shaken or stirred.

Here's the 34-year-old version of the "Remmington Steel" stud at an awards show back in 1987 (left) -- and 26 years later, the 60-year-old ".007" star at a gala last month (right).

We gotta ask...

Bar Refaeli First Post-Surgery Bikini Sesh

Guess Bar Refaeli is feeling better after going under the knife ... 'cause hours after she had a mole surgically removed from her torso, the supermodel was galavanting around in her bikini.

Bar originally posted a pic in a doctor's office on November 12 -- with the caption, "Goodbye beauty mark." It's unclear why the 28-year-old had the mark removed.

But hours after the procedure, Bar posted another couple of shots ... showing her running around the beach in a bikini with a bandage on the spot where her mole used to be.

Supermodels -- they even make recovering from surgery look easy.

Lady Gaga I'm Just Like Heidi Klum ... Old and Wrinkly

0-3iicferi

Lady Gaga stole a page right from Heidi Klum's fashion playbook last night -- strolling New York City dressed as an old, feeble lady ... only problem is when Heidi did it, it was a Halloween joke.

Gaga shuffled out of the Ritz Carlton Hotel wearing a shiny purple ensemble with a weird grey wig.

Our photog tried to ask about reports she'll be singing in space -- but the pop star was so committed to the old lady role, she refused to break character ... and replied, "You're from space?"

The whole thing was bizarre -- but we gotta ask ...

Karlie Kloss vs. Gisele Bundchen WHO'D YOU RATHER?

Here's the reportedly 6'1" American made super model Karlie Kloss (21) towering over the reportedly 5'11" Brazilian bombshell -- and mother of two -- Gisele Bundchen (33) at an awards ceremony in New York City last night.

They're both tall -- but the big question ...

Kate Upton Naked. Body. Paint.

Here's Kate Upton ... basically naked ... with some strategically placed body paint.

You're welcome.

Kate got all painted up for a Sports Illustrated photo shoot -- in the footage, Kate's trying to recreate one of the mag's most famous Swimsuit Edition covers.

We think she nailed it.

"I definitely feel naked," Kate said during the shoot ... "Because I am."

Kate said the artists took a particularly long time to paint on the necklace on her boob area ... yeah, can't imagine why.

'Thor' Star Jaimie Alexander ALMOST NAKED ... at Movie Premiere

So ... Jaimie Alexander won the "Thor" premiere last night.

The 29-year-old actress -- who plays Lady Sif in the movie -- rolled up to the El Capitan Theater in Hollywood wearing a dress that BARELY covered her lady junk.

Asgard ... meet Ass-guard.

Julianne Hough Wearing Whiteface

Julianne Hough was virtually make-up free and, more importantly, smoking hot yesterday in Los Angeles ... the perfect way to make people forget about that whole blackface Halloween thing.
Hough casually strolled into a gym Saturday afternoon flashing her mid-riff ... doing her best to move on from getting slammed for dressing up as Crazy Eyes from "Orange is the New Black."

Considering Julianne apologized for the costume, and how good she looks in workout wear -- we gotta ask ...

2013's Hottest Costume WHO'D YOU RATHER?

The most popular costume this Halloween season is Miley's iconic MTV Video Music Awards onesie... and although there were a lot of celebs that hopped on the bear-inspired bandwagon these were the hottest ones we could find.

Here's Miley Cyrus making waves as the OG costume creator (left) -- with Beacher's Madhouse master Jeff Beacher (center) -- and the sovereign socialite Paris Hilton embracing the same grizzly get up (right).

The question is...
