Seven-time F1 world champ Lewis Hamilton, 41, was ‘hard launched' on Monday by US model and reality show star Kim Kardashian, 45, following months of dating rumours.

In a series of pictures and videos shared by Kardashian to her 345 million Instagram followers, Hamilton is seen enjoying a fun bicycle ride with her in New York.

In the video, Kardashian and Hamilton are all smiles as the former struggles to keep up with the Ferrari driver before crashing into him after losing balance while attempting to pose for a picture.

This is the first time that Kardashian has shared a post featuring the F1 superstar after reports emerged earlier this year that the two were dating when they were spotted together at a New Year's Eve bash in Aspen. The couple have since been seen together in Japan, New York, and Los Angeles. They were even rumoured to be moving in together after being spotted shopping for home furnishings in April.
