EARTH ANGELS: Environmental “It” lensman Sebastian Copeland made the rounds in Los Angeles last week with cousin Orlando Bloom in tow. The two chatted with Larry King for CNN and rubbed elbows at the Jan Kesner Gallery, which is displaying photographs from Copeland’s book “Antarctica: The Global Warning” until Dec. 15. IWC and Max Studio sponsored the gallery’s opening party Friday evening. Copeland and Bloom capped off the night at the Chateau Marmont, where Brittany Murphy and Miranda Kerr joined their celebration.
