Twilight

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.

Question is ...

"Twilight" star Kellan Lutz fine tunes his ridiculous physique with a ridiculous workout ... in a PLAYGROUND! We can all agree -- monkey bars were NEVER put to better use than this.

"Twilight" actor Kiowa Gordon was on a road trip to L.A. for a big movie audition when he was arrested Monday morning -- and even though he missed the casting call ... sources say producers are willing to give him a second chance.

TMZ spoke with Kiowa's mom Camille -- nice lady -- who tells us Kiowa and his buddy were driving from Arizona to Hollywood so her son could try out for a non-Twilight movie on Monday afternoon.

As we previously reported, Kiowa's ride was pulled over for a routine registration check in Tempe -- and when the cop noticed there was an outstanding warrant out for Kiowa's arrest stemming from an incident in 2010, he was taken into custody.

But Kiowa MAY get a second chance at the movie -- because Hollywood sources tell us producers agreed to reschedule the audition after learning about Gordon's situation.

Kiowa was bailed out of jail Wednesday morning -- and we're told he'll once again attempt to travel to L.A. some time this week -- this time for a "Twilight" photo shoot.

Actor Kiowa Gordon -- who plays shapeshifting werewolf Embry Call in the "Twilight" movies -- was arrested in Tempe, Arizona early Monday morning ... this according to the Tempe Police Department.

Gordon was NOT busted for DUI, as reported by local AZ media -- but rather, he was arrested for an active warrant stemming from a drug paraphernalia possession arrest in 2010.

Law enforcement sources tell TMZ ... the 21-year-old actor was a passenger in a vehicle that was stopped for a "routine registration check" in Tempe around 6:12 AM.

During the stop, cops discovered there was an active warrant for Gordon's arrest -- so they took the actor into custody and booked him into a local jail.

10:00 AM: TMZ has obtained the police report from Gordon's 2010 arrest ... in which the actor was popped for carrying a glass marijuana pipe and for being in possession of alcohol while he was underage.

According to the report, Gordon's beverage of choice was Four Loko -- a drink that has been banned in several states.

"Twilight" star Taylor Lautner just gave the world one more reason to hate him -- because the 19-year-old just bought one of the most badass cars on the planet ... worth more than $200,000.

According to sources, Taylor walked into an L.A. Mercedes-Benz dealership with his parents last Wednesday ... paid for a silver 2012 SLS AMG -- complete with gullwing doors -- and drove it off the lot that same day.

Score one -- a BIG, FAST, awesome one -- for Team Jacob.

The freshly sheared 25-year-old hung out on the set of his latest non "Twilight" film in Toronto earlier this morning.

One of them doesn't age.

See ... they really do suck.

It was all for a honeymoon scene in the upcoming "Twilight" flick "Breaking Dawn."

Sources involved in the situation tell us Rob and Kristen were on their way home from LAX airport earlier this week -- when they noticed several paparazzi weaving through traffic to keep up.

We're told ... the couple -- concerned for their safety -- ducked into a nearby police station, hoping the cops could help out.

The young hunk showed off his buff and hairless physique -- yet again -- on the set of his new non-vampire flick in Pennsylvania on Thursday.
