We honestly can't keep up with those two - they're like the Ross and Rachel of the celeb world - but things are looking rosy between the on/off pair judging by this snap of them looking loved-up on their romantic break.
The F1 star posted the picture of them standing in the Sistine chapel, along with the caption "This was a great day....truly humbled by the Sistine Chapel plus there with my wifey."
"My wifey?" Adorable.
Friends of the couple claim they're back together for good this time, with one friend telling The Mirror: "During the time Lewis and Nicole spent apart, he was absolutely distraught and he said that if he ever got her back he would never let her go.
"He adores Nicole. They are so in love. Their circle of friends think that now they’re back together they will be married within months."
Nicole recently revealed that she won't be returning as a judge on 'The X Factor' this series, after two years with the show.
