Paris Hilton arrives for the MTV Movie Awards in Los Angeles, Sunday, June 3, 2007.[AP]

UNIVERSAL CITY, Calif. - The ruby carpet outside the MTV Movie Awards was swarming with stars Sunday, but all cameras were aimed at one who wasn't up for any award: Paris Hilton.

The heiress, who must report to Los Angeles County Jail by midnight Tuesday, flashed her trademark coy smile as she posed for photos and talked with reporters.

"I'm really scared but I'm ready to face my sentence," she said. "Even though this is a really hard time, I have my family, my friends and my fans to support me, and that's really helpful."

MTV Movie Awards host Sarah Silverman cracked a crude joke at Hilton's expense to open the show. When the camera panned to Hilton, she was not smiling.

Then the focus finally turned to movies. MTV's irreverent mix of honors includes prizes for best kiss, best fight and best villain.

Jack Nicholson was the winning villain, capturing the Golden Popcorn trophy for his mobster role in "The Departed." The fight prize went to Gerard Butler, who battled "The Uber Immortal" in the epic "300." Will Ferrell and Sacha Baron Cohen won best kiss for their smooch in "Talladega Nights: The Battle of Ricky Bobby." They shared a long, passionate kiss — culminating in a roll-around-on-the-floor makeout session — as they claimed their awards.

Cohen also won a Golden Popcorn for best comedic performance for his role in "Borat: Cultural Learnings of America for Make Benefit Glorious Nation of Kazakhstan."

"Unfortunately, Borat can't be here tonight," Cohen joked. "He's been feeling the pressures of fame and had to check himself into rehab."

The live program, held at the Gibson Amphitheater, was punctuated by a performance by Rihanna and Jay Z, who paired up on her new song "Umbrella."

Two "Dreamgirls" stars, Oscar winner Jennifer Hudson and Grammy winner Beyonce Knowles, were in the running for best performance. Also nominated were Will Smith for "The Pursuit of Happyness," Keira Knightley for "Pirates of the Caribbean: Dead Man's Chest" and Butler for "300."

Smith's 9-year-old son, Jaden Smith, claimed the breakthrough performance prize for his role opposite his father in "The Pursuit of Happyness." He accepted his award by video from Toronto with his dad by his side and his mom behind the camera.

Films nominated for best movie were "300," "Pirates of the Caribbean," "Blades of Glory," "The Devil Wears Prada," "Little Miss Sunshine" and "Borat."
