Fifty Shades of Grey

There's a couple of banging bandits on the loose in Vegas -- after they got busted celebrating "Fifty Shades of Grey" all over a Sin City museum ... which may seem appropriate, but it's still illegal.

TMZ obtained surveillance video of their bare-assed exploits around the Erotic Heritage Museum -- which was featuring an homage to kink on Valentine's Day ... and after-hours the couple went on a room-by-room sex spree.

First, they found a hiding spot and waited for the museum staff to clear out ... and the house lights to go down. Then the banging began in earnest. The couple didn't hold back as they moved around -- but they didn't realize security was watching.

Dr. Victoria, who heads up the museum, tells us security alerted staff members who returned to bust the exhibitionists. You gotta see their half-naked getaway once they realized the jig was up.

Dakota Johnson has joined ISIS ... well, at least a character she played on "Saturday Night Live" -- and the Internet went CRAZY!

Check out the video ....Dakota's dropped off at the airport by her dad -- played by Taran Killam -- but instead of joining the army like the Toyota commercial ... she joins the infamously savage org.

Social media users blew up with anger ... with responses like:

- "I think it's safe to say I will never watch SNL or any of Dakota Johnson's movies ever again"

- "Dear #SNL, jokes about Isis are not funny. See how much you laugh when you have to see your loved one(s) being slaughtered. No respect."

- "Actually offended by the ISIS sketch... Is that seriously all you could come up with? @nbcsnl #SNL"

So we gotta ask ...

Lolo Jones -- U.S. Olympian and self-proclaimed virgin -- says "Fifty Shades of Grey" is an abomination ... and people should boycott the movie because it glamorizes unholy sex.

Jones -- who's also a devout Evangelical Christian -- went to Twitter and wrote, "Funny how some people think there's nothing wrong with 50 shades of Grey. God didn't create sex for that purpose."

She added, "Watch another movie."

Jones then explained her stance ... saying the movie's hypersexual plot makes people feel that sex for pleasure is the answer to emotional pain.

"Some ppl medicate pain by being more and more physical to where if they are ever alone they can't feel any peace," Jones wrote.

The tweet is in direct contrast to Russell Wilson, another devout Christian who says it's not only OK to see the movie ... but admits he took in a screening last week and said he thought it was "great."

Russell Wilson is on the defense -- claiming he's NOT a godless infidel ... just because he saw "Fifty Shades of Grey."

The outspokenly religious Seattle Seahawks QB has been under attack on social media Friday morning ... ever since he revealed that he went to a screening of the sexually charged S&M flick on Thursday.

Some of the comments directed at Wilson were harsh:

-- "I'm more than a little confused, Russell. I thought you professed to be a Christian.
-- "Really? I'm honestly not sure how you can quote bible verses all the time and then say this is a good movie..."
-- "Don't say you represent Christ, and the publicly endorse a moved filled with immorality and sexual violence."
-- "COME ON MAN!!! THAT MOVIE IS MORAL FILTH!!!"

Well, Russell heard the critics loud and clear ... and decided to respond with the following statement:

"Saw a movie filmed in the town I call home. Provocative/disturbing no doubt but that does not make me less Faithful. Have a blessed day!"

Then, Wilson doubled down ... saying his favorite movie of all time is "Scarface" ... the cocaine-centric gangster classic.

The world is so cold and unfair, and Prince made it that way ... by forcing model Abigail Ratchford to remove her nearly naked Valentine's striptease from Instagram.

Ratchford pulled out off all the stops for a "Fifty Shades of Grey" style Valentine's Day striptease -- which is awesome -- but unfortunately she set it to Prince's 1991 hit "Gett Off."

It's ridiculously hot, but nobody uses Prince but Prince. Sources close to Abigail tell us his label, NPG Records hunted her down and demanded the video come down immediately.

Prince notoriously scrubs unauthorized use of his music from the 'net ... and apparently there's no "smoking hot" exception. Still, 30,000 people LIKED the clip before its demise.

Abigail reposted the vid with a different song -- Janet Jackson's "Feedback" ... but it's just not the same.

Seriously, Prince ... we thought you, of all people, would appreciate a "Sexy M.F."

Dwyane Wade could be trading basketballs for Ben Wa balls -- the NBA star tells TMZ Sports he's taking Gabrielle Union to see "Fifty Shades" this weekend because "I wanna learn something!!"

This clip is awesome ... Wade (who's out in NYC for NBA All-Star Weekend) told us he's not gonna let his new wife drag him to see the movie -- instead, he proclaimed, "I'm taking HER!"

"I wanna learn something," Wade said ... "I'm married! You gotta keep it up!"

#LearnTheSafeWord

Welcome to the gun show ... "50 Shades of Grey" star Jamie Dornan proved his body is definitely hard core enough to play Christian Grey.

Dornan's muscles look like they are about to explode in this impressive pic of him balancing his entire body weight on a workout bench. He says he held the pose for about 2 secs before collapsing in tears. We doubt that.

If '50 Shades' fans were worried JD wasn't hot enough to pull off the role ... they ain't worried any more.

"Fifty Shades of Grey" will fall short by $14 ... because the star's mom, Melanie Griffith will NOT be seeing the movie.

Melanie was leaving Madeo Tuesday night when our photog asked if she planned on catching the flick -- which stars her daughter Dakota Johnson -- but she said no, for 2 reasons.

Here's what's shocking ... back in the day Melanie sexed it up in "Body Double," though true enough, she didn't get Ben Wa balls shoved up her woo-ha.

The first trailer for mommy porn "Fifty Shades of Grey" might be exciting some lonely fans -- but serious BDSMers aren't ready to peg the movie for success ... because to them it kinda looks like amateur hour in the ole dungeon.

Don't ask how, but TMZ got in tight with some members of the Threshold Society -- a BDSM/leather club in L.A. -- and they say overall reaction to the trailer is ... where's the good stuff???

Threshold's corporate secretary (for reals) Azurell says the buzz from members is there are tons of other books and movies that better reflect their lifestyle -- and based on this first taste ... 'Grey' looks kinda "vanilla."

Azurell adds ... the movie could use more of their specialties -- light bondage, caning, needle play, fire play, and pegging. We're not telling you to Google that last one. Especially at work.

Over at Hollywood's Bar Sinister ... pro dom Feenix says 'Grey' has gotten a rise out of people in their 40s. He says more middle-aged couples are lining up for their loft area. Think VIP ... for people who want a good spanking. Or a bad one.

Seriously, don't look up pegging.

Bad news for fans of Tim Lincecum and "50 Shades of Grey" -- you've just missed your chance to buy the right-hander's Seattle condo ... which is located in the SAME building Christian Grey lives in the book.

The 29-year-old ace dropped $1.575 mil on his hometown apartment weeks after he won the World Series back in 2010 ... and just unloaded the place for a cool $2.25 mil -- about $225K shy of what he was originally asking.

The 2,442 sq ft pad sits on the 28th floor of the Escala building ... which treats its residents to a private spa, gym with a yoga studio, a catering kitchen and dining hall, a massive private theater, and a dog run.

Inside the apartment you'll find ... a giant master suite with walk-in closets and spa-like bathroom ... an open kitchen with custom cabinetry ... granite counters ... and cherry hardwood floors.

There's also a sweet wrap around deck that rounds out the condo -- which features incredible views of downtown Seattle, the Puget Sound, and the Olympic mountains.

"Sons of Anarchy" star Charlie Hunnam harbors no grudges ... giving nothing but props to fellow actor Jamie Dornan -- who will be replacing him in "Fifty Shades of Grey."

But here's the deal ... Charlie hasn't seen a frame of Jamie's work. So how does he know Jamie will kill it? It's all about the person doin' the pickin.'

Here's 31-year-old model/actor Jamie Dornan who was picked up to play Christian Grey in the erotic book-turned-movie "Fifty Shades of Grey" (left) -- and 33-year-old "Sons of Anarchy" badass Charlie Hunnam who made waves after he dropped the same role earlier this month (right).

If a woman can read "Fifty Shades of Grey" in public ... then a man should able to peruse a "Playboy" wherever he wants, so says famed author Anne Rice who tells TMZ she supports PORN EQUALITY!

Anne is a literary titan -- penning the books behind "Interview with the Vampire" and "Queen of the Damned" -- and she's also big into erotica.

Charlie Hunnam bailed on "50 Shades of Grey" at the last moment -- leaving everyone to wonder why he would leave the treasured role.

One interesting, yet completely unproven theory involves uhh ... little Charlie.

Charlie Hunnam appeared front and center for his friends wedding yesterday -- not phased at all over DROPPING OUT OF THE ONE OF THE MOST ANTICIPATED MOVIES EVER!!

Hunnam watched his buddy tie the knot in Santa Barbara yesterday ... just hours after Universal announced he was bailing on the "Fifty Shades of Grey" movie.

Charlie also gave a toast at the reception and was in great spirits ... according to reports.

No word on whether or not Robert Pattinson, Matt Bomer and Ian Somerhalder were invited.
