Nicole Scherzinger and Lewis Hamilton are reportedly giving their relationship another go.

The singer and Formula One racing driver broke up in October due to conflicting work schedules. Nicole and Lewis had been together on-and-off for four years.

Last week, they were seen having a frosty reunion in Los Angeles. After reportedly planning a "series of secret meetings over the next few weeks", sources say the pair are ready to give their romance another go.

"It's a struggle to maintain a blossoming relationship during the F1 season," a source told British newspaper The Sun.

"Lewis is so busy and in a different country every other week. When they can't see each other they use things like Skype, but that's no substitute for the real thing. With no F1 distractions, Lewis aims to spend some proper time with Nicole. He can't wait."

Lewis put on a brave face after his split from gorgeous Nicole. He insisted the photograph of them appearing uncomfortable in each other's company in Los Angeles wasn't a true reflection of their relationship.

"We still have very, very strong feelings for each other and I still love her very much. Who knows, maybe we will be together in the future?" he recently said.

"It was a really positive few days. I came away from LA feeling great and things are getting into perspective."

Nicole has been busy in her role as a judge on the US X Factor. She was recently linked to professional dancer Derek Hough and producer Christopher Mallick.
