Josh Brolin and fiancée pack on the PDA

Josh Brolin could barely keep his hands off fiancée Kathryn Boyd at the Los Angeles premiere of his new film “Everest” on Wednesday night.

Both decked out in dark ensembles, the Oscar-nominated actor, 47, kept close to his bombshell bride-to-be, as they perfected the step, kiss and repeat routine down the red carpet.

After dating for two years, Brolin popped the question to his former assistant this past spring. Back in May, the screen star and Boyd hit the Cannes Film Festival, where the fair-haired beauty flaunted her dazzling engagement ring for the first time.
