Barbara recently fuelled romance rumours with Lewis Hamilton after she shared a lingering embrace with him at the Hungarian Grand Prix last month. 

Formula 1 ace Lewis was first linked to Barbara in May, following rumours they fell for each other during the Cannes Film Festival. 

And adding fuel to the fire at the time, the stunning brunette posted a selfie on her Instagram wearing a Mercedes hat and the hashtag.

A source close to the model said the pair are getting on 'like a house on fire'.

'They hung out every day and partied at night. By the end of the trip they were really close,' the insider claimed. 'They’ve been keeping in touch, with plans to meet up again soon.'

However, Barbara isn't short on past admirers, having being linked with Niall Horan from One Direction and Justin Bieber.
