The couple have been snapped enjoyed a scrummy meal together at Yo! Sushi after Scarlett decided to debut her new look in public with her man.
Alongside the picture, which Scarlett has shared on Instagram, she commented: "yosushi with the handsome one #greyhair #boyfriend #datenight."
After several weeks of preparation and planning, Scarlett revealed she had dyed her long brunette hair grey last night (26 May).
Opting for a cool ombre effect, her tresses are dark at the roots before fading down to a light grey tone at the tips.
We like it, and given that he is out with her in public, we're guessing Luke does too!
In April, Scarlett confirmed her relationship with Luke and it seems things are going from strength to strength.
A fortnight ago, Scarlett revealed that she and Luke are planning their first romantic holiday together after asking for tips on sunshine breaks.
We think they make a great couple, don't you?!
