Earlier this afternoon (12 March), the Formula 1 driver uploaded a sweet picture of himself and Nicole at The Sistine Chapel in Rome, Italy last month and added the caption: "This was a great day....truly humbled by the Sistine Chapel plus there with my wifey. #godisthegreatest #sistinechapel #blessed."
Both stars dressed casually for their day out sightseeing in the Vatican City, with 35-year-old Nicole wearing a studded beanie hat and a leather jacket.
Clearly Lewis took a few style tips from his fashion-forward lady, as he is sporting a pretty similar outfit!
The long-time couple - who briefly split up last year - are thought to have visited the renowned chapel during a Valentine's break in February and judging by this photo, they had a great time together.
And now that Lewis has dubbed Nicole his "wifey" could there finally be wedding bells on the horizon?
The showbiz pair split up last July and were each noticeably heartbroken over the split.
They rekindled their romance over the New Year and celebrated the start of 2014 alongside music producer Swizz Beatz and his wife Alicia Keys in a snowy location abroad.
And although the twosome tried to keep their reunion as low-key as possible at first, fans speculated that Nicole was back with Lewis after she posted a photo of herself on a snow mobile in January moments before Lewis uploaded a similar snap.
There's no fooling the super fans!
Given that they are happily together once more, we reckon Lewis should hurry up and put a ring on it and make Nicole his "wifey" for lifey!
