Formula One racer Lewis Hamilton has confirmed his split from pop star Nicole Scherzinger, admitting he is struggling to cope following their break-up.
Earlier this month, tabloid reports suggested the former Pussycat Dolls singer and the race driver, who went public with their romance in 2007, had parted ways once again due to their hectic schedules.
"I'm trying my hardest to be positive," the 28-year-old Brit told Sky Sports, "but I'm going through a really, really tough time at the moment with the loss of someone really, really special in my life. My world's turned upside down."
Hamilton is now trying to throw himself into his racing to take his mind off his heartache.
"I have a job to motivate my team. And if I come in with my head down and negative energy then that goes around to all my mechanics who work day and night, and I don't ever want that. So I'm really trying to pull myself together and keep my head up, but it's so hard to do."
The stars previously went their separate ways in 2011, but later rekindled the romance.
