London, July 17 - Former Pussycat Doll Nicole Scherzinger is reportedly "tired of fighting for" her relationship with Lewis Hamilton.

The 34-year-old was recently left furious after her boyfriend was caught partying with 10 girls in his hotel suite last week and is now said to have told friends she is having doubts about her future with the Formula 1 star.

"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," contactmusic. com quoted a source as saying. (IANS)
