An emotional Lewis Hamilton dedicated his victory at the Hungarian Grand Prix to ex-girlfriend Nicole Scherzinger, a month after their latest split.

"I feel like, the thought on my mind through the entire race was of someone really special to me. And I want to dedicate it to her," Hamilton stated during a Sky Sports interview.

When he was quizzed by the interviewer if that person was Scherzinger, he smiled and replied in the affirmative.

He then spoke about how it has been a very difficult time for him over the past few months.

"It's been the toughest couple of months in my life. So coming in to the race they [his parents] really wanted to lift my spirits keep my focus on and clearly it's not affecting my driving. But it just doesn't feel the same. A couple of years ago we were here together and I won, so I have great memories," he confessed.

The 28-year-old former Formula 1 world champion with McLaren-Mercedes began dating Scherzinger after the MTV Awards in 2007. However the relationship was complicated by conflicting schedules and the vast distance between the pair's bases - Scherzinger lives in the US and Hamilton in Switzerland.

In January 2010, the two were reported to have broken up and the same speculation surfaced in October the following year. The two were then reported to be on the verge of breaking up last summer as well, when the former Pussycat Dolls singer confronted her boyfriend about his infidelity. The couple stuck it out that time but it seems they've finally given up the ghost.

The split surfaced only a week after reports suggested that the Formula 1 star was ready to propose marriage.

Meanwhile, Hamilton has been spotted partying with other women at the Playboy mansion in Los Angeles. Scherzinger, however has confessed that she was left feeling lonely after the break-up.

"I don't have anyone here, I don't have my family, I don't even have any friends here. My publicist is my closest friend," Scherzinger said.

"It gets lonely but I'm working all the time. If I'm not doing X Factor I put myself in the studio or I also love good food, so I'm getting to explore lots of different restaurants here. I take my publicist and my assistant as my dates, literally," she added.
