Ian Somerhalder and Nikki Reed don't just eat healthy ... they look damn happy doing it.

Ian and Nikki hit up the Farmer's Market in Los Angeles Sunday and the newly minted couple couldn't contain their happiness with fancy juice drinks in hand.

We're guessing it's because they both realize how hot their significant other is.

The couple's taking things to the next level ... attending the Creative Arts Emmys together Saturday -- and even adopting a horse.

Sylvester Stallone is destined to do an "Expendables 15" if genetics has anything to do with it ... because we got photos of his 92-year-old mom doing CrossFit!

Jackie Stallone is a certified bad ass ... with no machine in the gym out of bounds.

During her workout, Jackie hits the rowing machine, rings, medicine ball ... and even gets in some squats before knocking out a few bench presses.

Chris Brown is enjoying life again as a totally free man ... who is also totally free of abs. Turns out not EVERY guy who does time, comes out looking diesel. Why?

It's kinda like real estate -- location, location, location! We should explain.

Alex Pettyfer pissed off a group of jacked up dudes working out at Muscle Beach in Venice ... and we got video of their heated exchange.

Pettyfer was passing the famous weight lifting hangout when he asked the guys working out how much they lift. For some reason, a few of the lifters took offense ... and both sides started arguing.

In the video, one of the lifters accuses Alex of talking "s**t" ... which the "Magic Mike" star adamantly denies.

The musclehead who mainly argued with Alex tell us ... it started when the actor asked him how much he lifted. The dude lashed back, "How much do you make?" For some reason that triggered the argument.

Eventually Alex left after the two sides worked things out.

Shortly after the incident, the lifters told our photog it was just a misunderstanding ... and they've got nothing but love for Pettyfer.

Lea Michele stepped out publicly for the first time with her new guy Matthew Paetz ... but the photos look about as genuine as Matthew's claim that he wasn't a gigolo.

The pics show Lea and Matthew, guns out, on a leisurely hike -- and look like classic set up shots pre-planned with photo agencies. They're even wearing matching sneakers.

Our take -- Lea is screaming to the world she doesn't care about Paetz's past -- remember he claims he was only coaching gigolos, not doing the gigoloing himself.

A paparazzo was arrested for allegedly threatening the life of a huge celebrity trainer ... and then ominously reaching for what the trainer believed was a deadly weapon.

Harley Pasternak -- who trains Kanye West, Katy Perry, Miley Cyrus, Usher, Rihanna and a slew of other celebs -- told cops paparazzi showed up at his home Sunday because they got a tip he was about to train Robert Pattinson.

Harley says he told the paps Pattinson wasn't coming to his house but they didn't believe him. The paps got more aggressive and came onto his property. Harley told police he then walked out and ordered the photogs to leave, and that's when the photog in question threatened, "I'm gonna kill you and your family."

Harley says the photog reached for something in his car ... fearing it was a weapon, the trainer subdued the guy.

The photog denied making any death threats and insists Harley was the aggressor ... attempting to pull off his hubcaps with his bare hands. But a neighbor told cops she heard the death threat loud and clear. That was enough for police to hook the guy up and haul him to jail.

By the way ... the photog admits he was reaching for a weapon of sorts ... pepper spray.

Senator Claire McCaskill -- who grilled Dr. Oz like a cheeseburger during Tuesday's hearing -- was incredulous over the Doc's "miracle pill" because she's walked the walk ... sources connected to the Senate Subcommittee on Consumer Protection tell TMZ.

McCaskill lost a ton of weight in 2011 ... actually more like 50 pounds. She did it the old fashion way -- diet and exercise -- and she was proud of it. We're told she thinks diet shortcuts are ineffective and often fraudulent.

So when Oz came to The Hill ... we're told McCaskill was locked and loaded for a showdown over Oz touting green coffee beans as a miracle drug. One of McCaskill's staffers tells TMZ ... this was not a vendetta against Oz, and others have told us the same -- that she just thinks these quick fixes are harmful, especially when they're endorsed by credible people.

For Oz's part ... we're told he and his staff privately acknowledged he went too far on the air, and pulled back on the hyperbole several years ago.

President Obama wasn't going soft with those puny dumbbells, he was going smart -- at least according to the fitness guru behind "Body By Jake."

Jake Steinfeld weighed in on Obama's now famous workout in Poland -- and while a lot of people are giving the Prez crap ... Jake's giving him props for hitting the gym at all.

When we spotted Jake in Bev Hills ... he was quick to defend B.O. pumping iron with light weights ... because he says sometimes it's better to go for higher reps when you're squeezing in a quick workout on the road.

As for the President's chosen exercises and form -- you gotta hear why Jake was actually impressed.

He also reveals who he considers our "most fit" Commander-in-Chief ever.

Hint: It's NOT William H. Taft.

There was a major Secret Service breach this week in Poland ... because someone was able to sneak video of President Barack Obama working out at the gym ... and it's not pretty.

Obama, who is in Poland to rally Eastern European support against Russian aggression, was filmed working out in a hotel in Warsaw ... and somehow whoever took the video managed to do so without being made by Secret Service.

The workout is a little scattered -- some arms, some legs, some shoulders -- and his form could use some work.

Rob Kardashian plowed his SUV through a crowd of aggressive paparazzi -- none of whom work for TMZ -- as he exited an L.A. gym Thursday ... and you could clearly hear his car make contact with at least one of the shooters.

The situation was a mess from the beginning -- the photogs were gathered right in front of the exit driveway and forced Rob to make a decision ... stop and be shot ... or GO. GO. GO.

He went with Option 2.

The photogs refused to move at first, playing a game of chicken with the SUV -- only getting out of the way when it was clear Rob had no intentions of slowing down. Still, they hammered Rob with questions about Kim's wedding and his weight issues.

Fitness guru Cara Castronuova isn't very discriminating ... she'll go on a date with ANYONE who's willing to pay the asking price -- $10,000.

Cara -- an ex-trainer on "The Biggest Loser" -- tells TMZ she's raising money for her charity -- Knockout Obesity -- by offering a romantic evening in NYC with anyone who ponies up 10 grand.

The best part ... she's open to men and women.

Cara says she hopes to go on at least 3 dates so she can send 50 overweight kids to fat camp. She's moved by the heartbreaking letters she gets ... including one from a boy who told her he desperately wants to shed lbs so other kids will stop pinching his stomach.

So what do you get for your money? Cara says the date consists of dinner at a really nice place and then seeing the new Rocky musical on Broadway.

But here's the deal ... you have to pick up the tab for dinner ... and pay your own way to NYC. She'll take care of the theater tix.

Gerard Butler looks ready to do battle with Xerxes again, flashing his buff bod on Sydney's Bondi Beach yesterday.

THIS ... IS ... Atkins? Jenny Craig? More gym, less lunch?

Nikki Reed ditched her wedding ring and tucked her head between her legs Saturday in Los Angeles ... just a day after announcing her divorce.

Reed hit up a yoga studio yesterday in Los Angeles and seemed to be in a pretty somber mood -- makes sense, her and "American Idol" star Paul McDonald just ended their marriage.

The couple says they're still working on an album together ... but they've been living separately for the past 6 months.

Don't expect Megan Fox to wear mom jeans after popping out another kid last month ... because she already lost all the baby weight -- in 5 freaking weeks!

Fox ran some errands Friday in Los Angeles with her other son Noah -- after giving birth to Bodhi Ransom in February -- and one thing is clear, girl was looking GOOD.

Jillian Michaels and her crew got an unexpected surprise on her tour bus Sunday ... wild turkey.

Sadly it wasn't the fine bourbon ... it was a dead bird.

A turkey large enough to feed the entire "Sister Wives" group for Thanksgiving smashed into the bus windshield so ferociously ... it shattered the glass and went tumbling inside.

No humans were injured in the accident.

Jillian was travelling from Nashville to West Virginia giving motivational speeches on her "Maximize Your Life" tour.

Justin Bieber had his ass up in the air during his short stint in jail ... impressively doing 23 1/2 pushups in 28 seconds.

The jailhouse video -- obtained by TMZ -- shows Justin in his cell after being busted last month in Miami Beach for DUI and resisting arrest.

It's unclear what possessed him to show off his physical prowess, but he seemed excited about upping his cred.
