BUDAPEST, Hungary - Heartbroken Lewis Hamilton dedicated his victory at the 2013 Hungarian Grand Prix, his first win as a Mercedes driver, to his singer former girlfriend Nicole Scherzinger.Hamilton kept his title hopes alive with a comfortable win over Lotus’ Kimi Raikkonen (second) and Red Bull’s Sebastian Vettel, who was third.Despite the win, it was his emotional post-race dedication to former Pussycat Dolls' singer Scherzinger, which dominated the event's aftermath. Hamilton’s relationship Scherzinger ended earlier in 2013.‘WANTED TO DEDICATE IT HER’Hamilton said: "Winning is just the greatest, of course but I feel like the thought on my mind through the whole race was of someone who is special to me and I wanted to dedicate it to her."Asked if that person was Scherzinger, he nodded. "Yes, it's been the toughest couple of months of my life. Coming into the race, my parents were concerned for me and just wanted to try to lift my spirits and help me keep my focus. Clearly it's not affected my driving."I've been driving great and I've been very happy with how I've been qualifying for the last couple of races, but it just doesn't feel the same. A couple of years ago we were here together and I think I won, so I have great memories."‘USUALLY STUCK IN TRAFFIC’Hamilton and Scherzinger had a roller-coaster romance as they live on different continents and have demanding jobs. Hamilton said: "It's an incredible feeling and I'd like to thank all the fans here. My team did an incredible job, we studied a lot on Saturday night and were hoping the tyres would last."We had no idea it would go that well but I was hungry for it today. I was going all-out. Usually, I get stuck in traffic, but today I was going for every move I could. I wasn't having any of that."This has been one of the best and most important wins of my career."
