"Twilight" star Kiowa Gordon's penis is safe once again -- because the "revenge porn" site that published pics of the actor's nether regions has been taken offline ... following a full frontal legal attack.

The site -- IsAnyoneUp.com -- is known for "revenge" porn, allowing users to anonymously publish naked photos of anyone.

As for Kiowa Gordon -- pics of his naked body surfaced on the site earlier this week, showing the actor grabbing his genitals.

Kiowa immediately called his lawyers, who then fired off a cease and desist letter to the site.

The very next day, the website was purchased by an anti-bullying website -- BullyVille -- for an undisclosed sum, and now redirects to the BullyVille homepage.

It's unclear if Kiowa's cease and desist letter did the trick -- but we're told he's finally able to breathe ... because the pics are gone ... for now.

With the world going crazy for that other young adult love triangle movie, "Twilight" hunk Robert Pattinson sought some bearded, shirtless solace by paddle boarding in Malibu this weekend.

RPatz is enjoying his moment in the sun while he can.

"Twilight" stars Kristen Stewart and Robert Pattinson were spotted out in L.A. Saturday ... which would TOTALLY be a big deal ... if they were in "Hunger Games."

The same day news broke that his marriage to former "90210" star Jennie Garth was over, "Twilight" hunk Peter Facinelli was spotted out riding his motorcycle -- and no longer wearing his wedding ring -- in L.A. on Tuesday.

The couple were married for 11 years, have three daughters, but have yet to file divorce documents.

For now, Peter is riding off into the sunset alone.

Another celebrity marriage bites the dust ... this time "90210" star Jennie Garth and "Twilight" hunk Peter Facinelli are calling it quits after 11 years together.

The couple -- who have 3 minor daughters -- released a joint statement saying, "While we have decided to end our marriage, we both share the same deep love and devotion to our children."

The statement continues, "We remain dedicated to raising our beautiful daughters together."

We're told the couple has not filed divorce docs yet ... but it's just a matter of time.

Just when you thought "Twilight" fans had a healthy grip on reality -- TMZ has learned, lady Twihards are invading bridal boutiques, secretly lying about being engaged ... so they can try on a replica of Bella's wedding dress from the new flick.

The $799 replica is being sold in Alfred Angelo bridal boutiques everywhere -- and people who work at the chain tell us the scheming fans are driving them crazy, making it extremely difficult to conduct business.

By the way, we really don't think Twilight fans have a healthy grip on reality.

It's fun to say the "Twilight" movies are so bad they might be hazardous to your health -- but now that could actually be true!

According to several reports, the graphic birthing scene in "Breaking Dawn: Part One" has caused some moviegoers to suffer from seizures.

In Sacramento, a man told CBS13 he began to have a seizure during the scene and his wife described him as "convulsing, snorting, trying to breathe."

A man in Utah had the same thing happen to him, telling ABC-4, "I didn’t really remember what happened, after that I think I blacked out. According to [my wife], I was shaking and mumbling different noises."

Photosensitive epilepsy, which can be caused by flashing lights, is thought to be the cause.

Whether you are on Team Jacob with Taylor Lautner or Team Edward with Robert Pattinson, "Twilight" fans are hysterical over the release of "Breaking Dawn" this weekend.

Question is ...

Authorities still have no answers as to why "Twilight" star Jackson Rathbone and Flavor Flav both wore crushed velvet suits in public this week.

Rathbone stunned onlookers in a blood curdling burgundy two-piece crushed velvet catastrophe at the "Breaking Dawn" premiere in L.A., while Flav went with a deadly emerald version to Heavy D's wake in NY.

They say it takes three instances to make a trend ... let's hope not.

Robert Pattinson, Taylor Lautner and Kristen Stewart all hit the red carpet at the London premiere of "Breaking Dawn" last night ... but it was some half naked model/reality star who stole the show.

The chick sporting the side boob ... side hip ... side leg ... is Lauren Pope.

No, she's not in the movie ... but damn -- maybe she should've been.

"Breaking Dawn" babes Ashley Greene and Nikki Reed vamped it up at a press event for the film in San Francisco this week.
