Mariska Hargitay is paying tribute to the late Queen Elizabeth. The 58-year-old actress wore a deep purple suit to the “Law & Order” red carpet, which was a subtle nod to the late monarch. “I’m feeling very regal today,” she told Access Hollywood. “My respects, my love.” The actress also talked about reuniting with Christopher Meloni for the “Law & Order” crossover event, where “Law & Order,” “Law & Order: Special Victims Unit” and “Law & Order: Organized Crime” join forces for a supersized premiere. The historic “Law & Order” crossover event begins Thursday Sept. 22 at 8 p.m. on NBC.
