Paris Hilton can't catch a break. After pleading guilty Monday to two misdemeanors in her Las Vegas cocaine case, Japanese officials have delayed Hilton's entry into the country, the socialite's spokeswoman said. The 29-year-old star was stopped by immigration authorities, who are considering refusing Hilton entry into Japan because of her drug charges and sentence.

She was scheduled to appear at a news conference in Tokyo on Wednesday to promote her fashion line, but that appearance was apparently canceled. Hilton was forced to cancel her tour and returned home when she was denied entry at Tokyo's airport Wednesday following a drug violation in the U.S. -- running afoul of strict Japanese laws that have tripped up celebrities from Paul McCartney to Diego Maradona.

"I'm going back home, and I look forward to coming back to Japan in the future," a smiling Hilton told reporters before departing on her private jet.
