Here's eternally youthful supermodel Christie Brinkley, 58, at an event in Hollywood on Wednesday (left) -- and former "Heroes" star Ali Larter back when she was 33-years-old in 2009 (right).

A 25 year age difference never looked so flawless.

Here's "Judge Judy" star Judith Sheindlin, 69, in NYC on Wednesday (left) -- and cutting edge popstar Lady Gaga in Taiwan on Wednesday as well (right).

It ain't easy being green.

George Clooney and Steve-O's ex-girlfriend Elisabetta Canalis got on all fours while tanning her slammin' single body in a purple bikini in Cannes on Tuesday.

Joey Lawrence is taking it all off ... or most of it at least ... because the 90s heartthrob just inked a deal with the man-stripper crew at Chippendales in Vegas.

A rep for the beefcake brigade tells TMZ, the 36-year-old former "Blossom" star will don the legendary bow tie ... and not much else ... for a special engagement at the Rio from June 7th-24th.

We're told Joey will sing, dance ... the "whole nine yards."

Joey's celebrity MC predecessors at the famed strip show include 98 Degrees singer Jeff Timmons and former "Bachelor" star Jake Pavelka.

It's unclear how much Lawrence is getting paid for the gig -- but in those parts, there's only one currency ... singles.

Believe it or not, but "sleazy" popstar Ke$ha put away her usual ragged outfits, torn stockings, morning-after smeared makeup and ratty weave to do her best Blake Lively impersonation by bathing and glamming it up at an event in Beverly Hills last night.

The 25-year-old looks great, now if she could only do something about her music.

Just a couple weeks ago, the 37-year old former Tiger Woods mistress one-upped Demi Moore's famous Vanity Fair cover by posing in a sheer sheet ... and while flashing a thong.

Britney Spears spoke to FOX cameras before she took the stage at yesterday's Upfronts ... and she did so while chewing a piece of gum. Ding dang, y'all!!!

Britney ditched the gum by the time she went in front of the advertisers ... so clearly someone caught a glimpse of Brit's red carpet faux pas and corrected it.

For what it's worth ... Simon Cowell was chewing away too!

The gum wasn't the only thing Britney was chompin' on during yesterday's festivities -- Brit took a few bites out of her fingernails, too.

Despite the unwavering support from her new boss Simon Cowell, Britney seems to be taking out her pre-show anxiety on her cuticles ... a problem she's been dealing with for years.

In fact, Britney made a New Year's resolution to drop the habit in 2008, saying ... "Next year, I have to learn to stop biting my nails! I would like to stop worrying so much, because I worry all the time."

The chick featured in this photo is NOT in "Men In Black 3" ... but she showed up to the premiere in Germany anyway ... and ABSOLUTELY NOBODY complained.

Sporting a necklace ... and some garbage bag strips attached to other garbage bag strips ... German bikini model Micaela Schaefer walked the same red carpet as Will Smith and Josh Brolin on Monday.

Despite snagging Britney Spears and Demi Lovato for "The X Factor," former "American Idol" honcho Simon Cowell has hit a new low ... cut top.

While arriving to the "Britain's Got Talent" afterparty at the Dorchester Hotel in London last night, the 52-year-old mogul -- and his pack of Kool cigs -- nearly had a nip slip as his severely unbuttoned shirt showed off his sexy hairy man-bosoms.

Four months after giving birth, "The Help" star Bryce Dallas Howard was spotted exercising her post-pregnancy legs on a walk with her adorable baby daughter Beatrice in L.A. this weekend.

The 31-year-old -- who also has a 5-year-old son with hubby Seth Gabel -- kept it casual on her mother-daughter afternoon excursion in a pair of comfy sweats and slippers.

Bryce -- who's currently nominated for an MTV Movie Award for "Best On-Screen Dirtbag" -- knows raising two kids is a total workout.

Former "Hills" star Audrina Patridge celebrated her 27th birthday at Wet Republic at the MGM Grand yesterday ... by donning her customary two piece outfit.

Like some parts of Audrina, seeing her in a bikini never gets old.

Tennis great Andre Agassi has still got game.

Here's the 20-year-old eight-time Grand Slam champion back in 1990 (left) -- and 22 years later, the 42-year-old at the Kentucky Derby last week (right).

It's Andre by a hair.

Three of the babes on the guilty pleasure TV show "Revenge" -- Ashley Madekwe, Emily VanCamp and Christa B. Allen -- put away their claws and made nice at an event in West Hollywood this week.

Question is ...

Arnold Schwarzenegger showed up to his daughter's graduation from USC yesterday sporting some new facial hair that is clearly not indicative of a mid-life crisis.

Sorry ladies -- and some gentlemen -- but the real sexiest man alive Ryan Gosling is still dating his hot & sultry girlfriend Eva Mendes ... and they are letting the rest of the world know it.
