His relationship with Nicole Scherzinger may well have ended, but one four legged remnant of their stop-start romance was evident as F1 ace Lewis Hamilton strolled through Heathrow Airport on Saturday – their beloved pooch Roscoe.

The distinctive bulldog was joining his famous co-owner on a trip to Frankfurt – and he had good company in the form Coco, the latest addition to the Hamilton menagerie.

Lewis’s new pup was seen snoozing behind the plastic mesh of a dog carrier as the driver hurried across the busy terminal to catch his flight.

Sporting a baggy red tracksuit and leather Aviator jacket, he appeared to be in a relaxed mood while a Heathrow employee laboured with a heavy looking trolley laden with suitcases.

The Formula One star was later seen checking his belongings at the Lufthansa desk, with Roscoe appearing to catch the eye of fellow passengers as he balefully waited for his owner.

Lewis later tweeted pictures of the two dogs enjoying the high life – quite literally – in his First Class digs on the plane.

In the first Roscoe and Coco are seen sprawled out on a cushion, while another sees them chilling out on Lewis’s chair and bed, a half full bottle of wine sitting between them on an arm rest.

The racer’s trip to Germany comes as sources claim he is being urged to rekindle his romance with X Factor judge Nicole.

‘Lewis’ family can see how much both of them are hurting and have encouraged Nicole to reopen the lines of communication with Lewis,’ a source told Star magazine.

‘His cousins visited her at The X Factor several weeks ago and spent a lot of time with her in her dressing room.

‘There was a lot of chat about them getting back together and about old times. Understandably for Nicole, things got emotional. They were together for years – there’s a lot of history.’

The former Pussycat Doll has been always remained open about the possibility of a reunion with Lewis.

“I hope so, I would love that,’ she previously said. ‘For now, we are just friends. But whatever the future holds, I don’t rule anything out. I also don’t have any regrets.’
