KARACHI: Pussycat Dolls Singer Nicole Scherzinger is reportedly ‘tired of fighting’ for her relationship with Lewis Hamilton.

X-Factor Judge Scherzinger, was recently irked after her Formula 1 beau Lewis Hamilton was caught partying with 10 girls in his hotel suite last week.

After the incident she flew back to London to confront Hamilton and is now said to be unsure about their relationship.

A source close to Scherzinger said, “Nicole's confiding in pals that she thinks it might be time to call it a day. It's a long distance relationship, he isn't ready to settle down and they're both working non-stop - she's tired of fighting for it and feels it just isn't working.” The same source later added that, “Nicole is so busy at the moment with promotional activity for her music on top of her role on 'X Factor'. It really hurts her that she has to take on a new job while feeling so humiliated. She is furious he could be so disrespectful to her. She's telling her friends that she doesn't think it's worth it. She hasn't wanted to speak to him for the past few days while she mulls it over.”

Scherzinger and Hamilton have had a somewhat troubled relationship since 2007.

“Nicole knows deep down that Lewis isn’t ready for marriage but because she loves him so much, she’s been trying to convince herself otherwise. It could be better if she moves on,” the source concluded.
