Nicole was snapped as she sat across from Lewis in a London restaurant while they caught up over sushi and red wine. Delicious!
Posting the picture on Instagram, Nicole told her followers: "#datenight #sushi."
Last month, Nicole moved permanently to London after landing a role in the West End musical Cats.
The former Pussycat Doll has been cast as Grizabella in the long-running Andrew Lloyd Webber show for 12 weeks and she trod the boards for the first time earlier this week.
Proving what a supportive boyfriend he is, Lewis made sure he was in the audience for Nicole's debut in Cats and later gushed about her performance on Instagram.
The F1 champion told his followers: "Went to see the Cats musical for the first time last night, and my lady @nicolescherzy blew me away!
"Such an incredible talent she is, as well as the rest of the cast! #Grizabella #JellicleCats #CantGetThatSongOutOfMyHead #SoGood #NicoleIsAmazing #London #GoSeeIt."
Nicole later replied: "Thanks so much for the love and support babe...purrrrrr @lewishamilton @catsmusical #Cats.'
Aww, they really are a purrrrect couple!
