‘All I Have’ hitmaker Jennifer Lopez certainly had all eyes on her at the 84th annual Academy Awards tonight.  The Billy Crystal-hosted affair, held at Hollywood’s ‘Hollywood & Highland Center’, saw J.Lo’s low plunging neckline courtesy of her Zuhair Murad gown.

Already one of the events most talked about subjects, Miss Lopez was one of many musicians rocking the red carpet of Hollywood’s biggest night.  Pharrell and J. Lo’s former boo Diddy were also in attendance.

Peep some pics below (thanks, in part, to Rap-Up):
