Whatever Halle Berry's taking ... it's working like a charm -- the 47-YEAR-OLD stepped out last night for the first time since giving birth to her SECOND kid ... looking like someone half her age.

Halle was at the Acapulco Film Festival in Mexico ... but her bod was the real show.

Halle and fiance Olivier Martinez welcomed son Maceo in October ... which is crazy enough considering Halle's age ... but even crazier because the pregnancy had ZERO effect on her physique.

In fact, it might have made her even hotter ... just look at those boobs.

Here's "Legally Blonde" lawyer Reese Witherspoon doing serious time in a safety-cone-orange outfit at a benefit in L.A. this week -- and Taylor Schilling's character Piper in her signature state issued scrubs from "Orange is the New Black."

Only one of them was actually arrested in the last year.

Refusing to age with even a hint of grace, 55-year-old Madonna clung desperately to her youth on stage last night with Miley Cyrus ... like a narcissistic mother trying to be hotter than her daughter.

It's just ... painful.

Madonna and Miley (who's 21 by the way) hit the stage together last night in cowboy get-ups for Miley's "MTV Unplugged" show in Hollywood ... but it felt more like a TLC special.

It's just the latest in Madonna's "I'm still hip" campaign -- in 2012, she named her tour "MDNA" an obvious play on MDMA ... and even once asked a crowd if they'd "seen Molly" ... a sad out-of-the-loop reference to the same drug.

Oh yeah, and a couple weeks ago she referred to her white son as "dis n**ga." Good lord.

Bad news for chubby chasers ... fat Jessica Simpson has been replaced ... with a hotter, skinnier version.

The 33-year-old mom strolled though JFK this week like it was 2005 all over again ... sporting a pair of tight leather pants that would even make Nick Lachey's head spin.

Despite her appearance, Jessica recently said she's currently 15 POUNDS HEAVIER than she was back in 2009 ... when she rocked the infamous mom jeans on stage at a concert.

Sure as hell doesn't look like it.

Jack Nicholson upped the ante on duck-lip selfies by shooting his own ... of course he did it from $2500 COURTSIDE Lakers seats! Take that 25-year-old chicks.

76-year-old Jack struck the tired-ass pose with a cute blonde fan last night at Staples Center.

This was probably the closest he came to smiling last night since the Kobe Bryant-less Lakers got crushed by the Indiana Pacers 104-92.

Our best guess on Jack's thoughts during the game ... "This town team needs an enema!"

CeeLo knows ... nothing gets a party started like half-naked women jumping up and down -- which is why the guy booked 3 hot chicks to work a trampoline at his Grammy shindig last night.

TMZ has footage from inside CeeLo's bash at Lot 613 in L.A. ... and it looked AWESOME -- with food trucks and a mobile barber shop ... and oh yeah, HOT CHICKS ON TRAMPOLINES!

CeeLo couldn't have been cooler -- and kicked it with our camera guy while he was gettin' shaved up for the party.

Gotta stay fresh.

Justin Bieber will never get a sweet deal with Proactiv again if he keeps screwing up ... but even if Justin turns into a choir boy, he's gotta 86 those pimples.

It's hard to miss the zits on Bieber's face in the now famous mug ... pretty ironic, considering Bieber was a spokesperson for Proactiv in 2012.

Proactiv co-creator Dr. Kathy Fields tells us, she's seen the mugshot and it's clear Justin's stress is causing him to break out ... so they're gonna send him some Proactiv+ and X-Out to help get him back on track.

As for him getting a full-on spokesman deal again ... Fields says they look for people who are in "the right state to help others and right now Justin needs to get himself healthy."

The Seattle Seahawks have one HUGE advantage over the Broncos in the Super Bowl ... their cheerleaders' asses are wayyy bigger -- this according to bona fide booty-expert Sir Mix-A-Lot.

The "Baby Got Back" singer tells TMZ Sports ... there is no competition between the teams when it comes to butt-size, saying simply "Seattle cheerleaders got the best asses."

Mix -- who's from Seattle -- is a diehard Seahawks fan ... but his views on the cheerleaders aren't totally biased ... 'cause the rapper admits the "Denver cheerleaders have the best t**ties."

Wearing an unfinished dress by the Michelin tire company, Paris Hilton hit up an event in Hollywood last night ... and modeled her svelte groin area for a crowd of strangers.

42-year-old mother of four and cancer survivor Brooke Burke-Charvet knows how to live life to the fullest ... and tightest ... flaunting her ridiculously toned body at a gas station in Malibu today.

Just to recap: this "Dancing with the Stars" badass is 42, she has 4 kids (3 daughters and 1 son) and recently beat thyroid cancer following a scary diagnosis in 2012. And she can still look this good.

FYI, Brooke is currently married to former "Baywatch" star David Charvet.

Gotta love California.

Freedom isn't the only thing Jason Trawick gained after breaking up with Britney Spears -- and he's not tripping one bit ... proudly showing off his new gut during a weekend pizza run in Hollywood.

Oh yeah, he got Popeye's too.

Spears and Trawick -- her former agent -- famously started dating in 2010 and were engaged the following year. Barely a year after that, they were single again.

What a waist.

As for the pizza ... our own Gary says, "All fat guys know ... you never eat the pizza out of the box right outside the store. C'mon man."

4:28 PM PT -- Jason just responded on Twitter with a big belly photo, writing, "Thanks @tmz I needed this. Started my diet/workout program today. C u in a month!"

You're welcome ... but a month's pretty ambitious.

Forget supermodel butt washer ... there's a new best job in the world ... SUPERMODEL BOOB HOLDER.

And just in time too -- Maryna Linchuk nearly suffered a wardrobe emergency on the beach over the weekend in St. Barts ... stripping out of her bikini and into another outfit ... and her loyal boob-covering attendant jumped to the rescue. No nip slips here! Unfortunately.

Brad Pitt's enlisted a military style haircut, but it's not just for a movie role -- BP now says there's another, more vain, reason for the new 'do.

Pitt cruised into LAX on Sunday looking like he was heading to basic training -- sporting a high and tight fade ... telling paps, "It's fashion, baby."

Truth is Brad's also shooting a World War 2 drama called "Fury" -- but does it really matter?

"Sleepy Hollow" star Nicole Beharie is begging for a lawsuit ... so says her stylist, who tells TMZ, she's on the brink of taking the actress to court after Beharie stiffed her on a HUGE styling bill.

Sharone Blades tells us ... Beharie hired her to style the actress for a Television Critics Association event Monday ... and agreed to pay $5,000.

Sharone says she did a bang-up job and Nicole loved her dress ... but has only forked over $2,000. Sharone says she confronted Nicole ... who countered by saying she didn't like the dress after all.
