Video: Lewis Hamilton shows off "preposterous behaviour" by smoking cigar

Formula 1 champion Lewis Hamilton has described his behaviour at last weekend's parade in Barbados as "preposterous".

The 30-year-old has been holidaying in the Caribbean after F1 shut down for a three-week break midway through the season.

During the annual Kadooment Day parade, Hamilton was spotted partying with popstar Rihanna, and now the sportsman has shared a video and photo of the festivities on his Instagram page.

Alongside an image of himself smoking a cigar while dancing with women, the Mercedes F1 driver wrote: "Positively preposterous behaviour I say!! #0FucksGiven #daggeringboss #BarbadosCropOver."
