Vanessa looked stunning in a black gown with sheer detailing while Austin opted for a sharp black suit.

“And we’re OFF!!!! To the @onceinhollywood premiere with my man of the hour @austinbutler,” Vanessa wrote on her Instagram.

The upcoming film visits 1969 Los Angeles, where everything is changing, as TV star Rick Dalton and his longtime stunt double Cliff Booth make their way around an industry they hardly recognize anymore. Austin portrays Charles “Tex” Watson in the flick, a central member of the Manson family.

Once Upon a Time in Hollywood hits theaters on July 26th.

FYI: Vanessa is wearing an Armani gown.
