Miranda Kerr had a busy day in sunny LA yesterday. First she met her husband Orlando Bloom at a gym in Beverly Hills. She wore a sexy spandex outfit with a red bra while Orlando rocked purple sweat pants. The couple arrived and once they wrapped up their workout, left separately. Later in the day, Miranda rocked tiny short shorts and a hot pink top to run errands. Miranda had an exciting weekend that included a candlelit dinner with friends in order to observe Earth Hour. Miranda was this year's global ambassador for the event, and her duties will continue when she hosts a public yoga class for 200 winners in Sydney on August 25. She's urging people to join her in supporting the Earth Hour cause throughout the year, and tweeted, "lights out for one hour is a great start however it is what we do beyond the hour that will make the real difference."
