Pattinson, who shot to fame by playing Edward Cullen in the vampire franchise, is always hounded by fans and needs added protection, reports contactmusic.
"We've all stayed so down to earth, and it's just funny to see life change for the people around us, especially Rob (Pattinson). It's like, when a fan lunges at him and you only see one bodyguard around, and then 10 more jump out of the crowd, where they've been hiding," said Lutz.
"God, it's crazy to think about needing a bodyguard, but Rob can't take any chances. He's a heartthrob, but he's also a great guy and we all love him because he hasn't changed as a person," he added.
