Johnny puts his feelings on display
The actor, 50, was supporting Amber, 27 – who stars in the thriller flick – at the bash and planted a sweet kiss on her cheek as they walked down the red carpet together.
He also held the stunning blonde’s hand while posing for photos.
It’s no wonder Johnny was so keen to show his affection for Amber – she looked gorgeous in a plunging black dress with a risqué side split.
Her locks were swept over one shoulder and her lips had been made up with a slick of red lipstick.
Johnny looked dapper in a blue suit, fedora hat and white brogues.
But it was the sparkling rock on Amber‘s left hand that attracted the most attention.
Johnny is rumoured to have proposed to Amber – who he met on the set of 2011 flick The Rum Diary – last month but the couple are yet to confirm their engagement.
