The days of Marky Mark have long since past, but Wahlberg proved he's still got it, while on the Miami set of Pain and Gain!

The Boogie Nights star looked sexy in a comfy white track suit, as he took a careful moment to adjust himself, before getting into a vintage Porsche with director Michael Bay to shoot a scene.

The father-of-four is required to be super-buff for the upcoming flick, in which he plays a bodybuilder, and he was seen earlier in the day getting spray-tanned on the balcony on his Miami hotel wearing just his underwear!

The action comedy hits theaters in April 2013, and centers on a pair of bodybuilders who caught up in an extortion ring and a kidnapping scheme that goes terribly wrong.

Hilary Duff is such a die-hard fashionista, that she even matched her $2,000 Goyard St. Louise tote with her low-key gym attire!

The new mom-of-one has been on a serious mission to drop the baby weight in time for bikini season, and she's been hitting up the gym nearly every single day.

Over the holiday weekend Hil and hubbie Mike Comrie left baby Luca at home for an adults-only weekend in Sin City, and enjoyed a full night of partying in the VIP booth at Surrender Nightclub in Encore at Wynn Las Vegas.

Is it just us, or is Duff getting trimmer by the day?

Paris Hilton and DJ Afrojack did not break up because the two were never dating.

The beautiful blonde heiress and the famous DJ are nothing more than friends. Earlier today, online reports claimed Afrojack had broken up with Paris. Hilton’s rep says these reports are "100 percent not accurate and are coming from inaccurate sources."

Afrojack has been working with Queen P on her upcoming album. Can't wait to hear those sexy tracks!

As for their current situation, the rep adds:

"Paris and Afrojack are best friends and love and support each other very much. Nothing has changed."

A source close to Afrojack and Paris tells X17 exclusively:

"The two are partying together this summer all around Europe with trips to St. Tropez and Ibiza. Afrojack loves Paris because not only is she hot, but she's the life of the party. He loves her energy."

The source adds, "Paris loves him like a little brother and thinks he's such a sweetheart and so talented."

Glad that’s all cleared up!

Chinese actress Zhang Ziyi, famous for her role in Crouching Tiger, Hidden Dragon, is being investigated over prostitution claims after a handful of reports claiming that she's been paid millions of dollars to sleep with wealthy Chinese businessmen, including former Minister of Commerce Bo Xilai and his associate Xu Ming.

According to a handful of gossip reports in China, Zhang slept with Xilai for 10 million Yuan (approximately $1.5 million USD), and they had at least 10 encounters in between 2004 to 2007. Zhang was reportedly introduced to other officials through Ming, and she's reportedly been paid $110 million over the years, according to Yahoo! Singapore and several other websites.

Zhang is currently shooting The Grandmasters in China, and the report claims the starlet has been barred from leaving the country while the investigations continue. Ziyi was noticeably absent from the Cannes Film Festival, where her upcoming movie Dangerous Liaisons was an official selection, but her rep insists the stories are completely bogus.

Ziyi's rep said in a statement:

"We read this outrageous report in the Hong Kong's Apple Daily. It sent stone-cold chills down our spines and has left us with a feeling of deep sadness. During the last month, Zhang Ziyi has been busy working day and night on the set of 'The Grandmasters.' Why should this devoted and responsible actress have to suffer this kind of slander and defamation? Friends have advised us to release a short statement and not take this seriously. The more you argue, the more you will stir up. It would be better to step aside until people lose interest and the lies disappear. The innocent will always be innocent.

But this time we don't want to be silent. If we leave these lies to spread, what is completely untrue will be at risk of becoming a half-truth. This time, we are telling those rumor-makers that we will respond. We will prove our side of the story; we'll seek legal justice; we'll find you in the darkest corner and go after you.

We will seek justice for Zhang Ziyi by taking legal action against Apple Daily and against any other media publishing these false reports."

We photographed the 33-year-old starlet back in 2009 vacationing with then-boyfriend Aviv "Vivi" Nevo in St. Barth, and while we doubt there's any truth to these claims, she certainly seems to be quite open about her sexuality! Not only did the starlet tan topless and remove most of her bikini bottom while tanning, but Nevo couldn't seem to keep his hands -- or his mouth -- off of her!

What does a parent do when he hasn't seen their kids in a while? Take 'em to the beach!

Well, that's what Matthew McConaughey did today as cameras spotted the 42-year-old actor at the beach in Malibu with his kids Vida and Levi. How cute!

The Magic Mike star has had a busy few weeks promoting his films Mud and The Paperboy at Cannes and looks like he was ready for some much needed R&R with his tykes! If he's on daddy duty, maybe Camila is enjoying a relaxing day at home?

Another day, another scandalicious photo shoot starring a half-naked Rihanna!

The 24-year-old R&B hottie covers the new issue of Esquire UK, and we got a sneak peek at her sexy pics last week, but here's the rest of them, along with a video you just have to check out. RiRi's interview with the men's mag hasn't been released just yet, but we'll let you know when it's out -- we're sure there's plenty of quotes that are just as naughty and controversial as these photos!

Looks like someone has the baby blues... and no, we're not talking about impending fatherhood, we're talking about the shirt!

We spotted Scott Disick out shopping in Calabasas today, and the preppy reality star papa kept it classic in seersucker shorts, an aqua collared polo, and penny loafers. The New York native had laser focus as he texted away on his iPhone, and we hope he was checking in with his pregnant girlfriend Kourtney Kardashian like a good man!

Although recent tabloid reports claim Mr. Disick's lying will lead the longtime couple to split, clearly Kim Kardashian trusts him enough to let him borrow her pricey ride! The hard partying bad boy whipped around in KK's white Ferrari, even though he has his own metallic version of the sports car.

First Bruce and now Scott... why does everyone want to borrow Kimmy's car?

Hot new couple alert?

Bar Refaeli and snowboarder Shaun White were reportedly spotted “dancing, hugging and kissing” at Sway in New York City over the weekend, according to Page Six. Sources told the paper the Olympic gold medalist was "distracted" and texting away on his cell phone until Leonardo DiCaprio's ex-girlfriend arrived around 1:30am, and the two spent the next hour and a half partying it up together.

Around 3am White walked Refaeli to her car, and he then returned to the club. Think we'll see these two together again? Or is Bar just hopping around?
