Lady Gaga stepped onto the red carpet on Monday night sporting a widow-esque black veil (above, left), and minutes later, celebrity photographer A.J. Sokalner was dead. Sokalner (above, right) was working the red carpet at the ACE Awards that the 'Poker Face' singer was attending in New York City when he collapsed just minutes after Gaga took to the carpet. He was pronounced dead at Bellevue Hospital shortly after, and the owner of ACE Pictures, who Sokalner worked for, says emergency workers said he had suffered a heart attack. He was in his late 50s.
