The X Factor judge was said to be upset with Formula One driver Hamilton over claims that he partied into the early hours of Wednesday morning (July 11) in a luxury suite at the Mayfair Hotel, entertaining a large group including ten girls.
Hamilton is said to have reassured Scherzinger that nothing untoward happened, with an insider telling The Sun: "They are not breaking up. Both are still committed to making the relationship work.
"Nicole was very upset Lewis allowed himself to be put in such a vulnerable position, because he should know what people will say and think when they see these types of pictures.
"But she accepts nothing went on in the hotel room."
The source claimed that the couple "still have their problems" due to "the sheer distances between them and their hectic careers", but added that Scherzinger's new role on The X Factor would mean they could see much more of each other as she will be staying in the UK until the end of the year.
