Nicole took a break from her duties as X Factor judge and flew out to Rome, Italy to perform at the city's Summer Music Festival.
Nicole teamed her heavily embellished dress with knee-high leather boots, and was beaming with joy as she sang her pop hits to the crowds.
The 34-year-old 'Boomerang' singer didn't just stick to the one outfit though, as she later showed off her toned legs in a fitted black lace dress for a performance with Italian recording artist, Eros Ramazzotti.
Nicole is no stranger to Italy, and when she visited the country last month, she embraced the tourist attractions of Milan.
This week, it was reported that her boyfriend, Formula One racing driver Lewis Hamilton, could be planning to propose to her next year, before the couple reach their sixth anniversary.
