Kristen Stewart may worry that Twilight Saga fans might "assassinate" her on the red carpet -- but her costar Kellan Lutz has slightly different Twi-hard encounters.

"A fan came to me with handcuffs and wanted to handcuff herself to me," Lutz told at Thursday's Eclipse premiere in London. "I was like, 'Oh! Interesting...'"

That wasn't the hunky 25-year-old's last kinky interaction. After he shared the handcuff tale with the press, "another fan later came to me and upped the ante," he said, "and brought some furry ones. [She] opened her robe up and had a little outfit on. That was fun!"

But Lutz -- who plays vampire Emmett Cullen in the saga -- doesn't mind red carpet hysteria. "I love this!" he gushed Thursday. "This is my first premiere in London, and I couldn't have asked for a better one. And I love the accents!"

The star (and beau to AnnaLynne McCord) doesn't take the global Twilight phenomenon for granted. "It really is an actor's dream. I give it all up to God for putting me here...It's been so much fun!"
