The 49-year-old Oscar-winning actor looked so handsome in an all black tux as he stepped out for the event.
Javier will be hitting the stage during the show to present an award.
The Oscars are being presented without a host for the first time in 30 years. The show kicks off at 8pm EST/5pm PST on ABC.
FYI: Javier is wearing a tux by Ermenegildo Zegna XXX.
