Other reports have similarly suggested his long-term attention might currently lie away from the track: "Lewis finishes up his F1 commitments in November and is planning to fly straight to the UK to be here for Nicole while she films the live X Factor
shows," said the source.
As for Scherzinger, comments from her carried in the tabloid press suggest that she's also unhappy about the break-up - but that she's made the first decision to put her work life first. "You just make those sacrifices and they made me feel so at home last year. It is hard but you always make those sacrifices and it's worth it.
"It gets lonely but I'm working all the time," she told The Sun
newspaper. "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."
The question now is whether or not Hamilton can find the same single-mindedness to put him back on track to winning more races and championships with his new team. Hamilton certainly has his supporters who insist he can do just that, which include broadcaster and former F1 driver Martin Brundle.
"He needs to find a way pretty soon to be able to package that up and be able to manage his private life and make sure he's maximising his racing life," Brundle told Sky Sports News
this week. "Lewis is still in there, [so] I wouldn't write him off.
"He's made a great decision it seems in going to Mercedes-Benz," he added. "He's got some points on the board so he's not out of sight already. He's got the pole positions [even if] the victories haven't come his way; two have gone to Rosberg of course, his team-mate, who's driving beautifully.
"There's a long way to go in this championship. Halfway through the Hungarian Grand Prix is halfway through the championship season, so many points to come."
