Lewis Hamilton rekindled his romance with Nicole Scherzinger because his dad told him to.
The Formula One ace - who split from the 'Don't Hold Your Breath' hitmaker in October after three years of dating - decided to give the relationship another try after his father Anthony advised him a "settled personal life" could help his motor racing career.
An insider explained: "Lewis' dad told him if he wants to win the championship again he needs a settled personal life. Lewis has been living it up since he split with Nicole last year. He's been attending a lot more F1 parties and enjoying the life of a famous millionaire sportsman.
"His family stayed close to Nicole during the split and his dad said all the partying could jeopardise his career. He pointed out that Nicole was an amazing lady and that she wouldn't wait around for long.
"Lewis has always been close to his dad and Anthony has managed his whole career from the start."
The couple reportedly parted ways due to the 33-year-old singer's desire to settle down and start a family, but it is thought the 27-year-old sportsman's newfound commitment to the relationship could mean a wedding is on the cards "by the end of next year".
The source added to the Daily Star newspaper: "Lewis is ready to settle down. He's had four months to live the life of a single millionaire Formula One driver and is now in it for the long haul.
"His family think there will be a wedding by the end of next year."
