COSY AND FLIRTY: Rita and Formula 1 star Lewis Hamilton.

Formula One champ Lewis doesn’t just move fast on the track.

The British hunk also races into new relationships, and has reportedly been enjoying his holidays with Rita Ora.

The sexy UK singer has fuelled speculation she is dating the driver after video footage of them having a private pool party emerged during a trip to Montenegro.

The 31-year-old sportsman could be seen with his arms around her and squirting the blonde beauty with a hose.

An onlooker told The Sun newspaper: “They looked very cosy and flirty.

“It was clear Rita had a couple of drinks and Lewis was loving every second of it.

“While they may not be a couple they were clearly enjoying themselves.

“They both had huge grins on their faces.”

Rita and Lewis flew back to the UK last week on his private jet.

The pair stayed at the singer’s family home on the River Bojana, with the singer’s father, sister, and cousin also on vacation there.

Rita, 25, previously dated Taylor Swift’s ex, DJ Calvin Harris.

Meanwhile, Lewis, who split from long-time girlfriend pop star Nicole Scherzinger last year, has recently been linked with a bevy of beauties, including reality TV star Kendall Jenner and models Gigi Hadid and Barbara Palvin.
