They were first seen partying together during the Cannes Film Festival earlier this month.

And Lewis Hamilton and Barbara Palvin were seen side by side again on Saturday - sharing a flirty exchange at the Monaco Formula One Grand Prix qualifying session.

Victoria's Secret model Barbara, 22, opted for a casual look on the sweltering day, donning tiny denim hot pants with a white top.

Lewis wore his driving suit as he had been competing in the Grand Prix qualifying session, where he took third position for his Mercedes team.  

The stunning model has been linked to Niall Horan, Harry Styles and Justin Bieber in the past. 

Arriving together in the same vehicle, the pair seemed to be in a hurry to access the venue, which has been frequented by various stars during the film festival fortnight. 

A spokesperson for Lewis Hamilton told MailOnline: 'Lewis and Barbara are friends and fellow L'Oreal Ambassadors.
