They were spied together on a number of occasions in Cannes last week.
And Barbara Palvin has not left her bonding time with Lewis Hamilton at the film festival, as the pair were spied heading to the beach in Monaco on Monday.
The 22-year-old model was spied getting dressed after seemingly enjoying a dip in the waters while the British Formula 1 ace, 31, stripped down to show off his muscular frame.

Looking totally relaxed, the Hungarian model slipped into just a simple grey T-shirt dress having seemingly enjoyed a dip in the warm waters.
Her hair was sodden, tumbling in simple waves around her shoulder while she opted to forego make-up entirely for her trip on the shore.
Prior to slipping into her grey T-shirt dress, the pretty starlet sported a stunning frilled Bardot top, proving her attention to sartorial detail extends into every day.
She toted a stunning black handbag, with a leather body and intricate detailing, while she rocked huge round lens sunglᴀsses shielding her face.
While Barbara was relatively covered up in her T-shirt dress, Lewis was flashing it all as he showed off his phenomenally honed sportsman’s physique.
Wrapping himself in a towel, he showed off his heavily tattooed frame as he bent over while also highlighting his muscular back.
In a cheeky display, Lewis pulled on a red baseball cap emblazoned with the words ‘New F***ing York’ across the front – partially shielding his famous face.
Prior to stripping off he sported lilac Aztec print shorts with a baggy white vest as he chatted away to a pal before turning his attentions to his close pal Barbara.
Just days before, the duo, who are both L’Oreal Ambᴀssadors, were snapped at Gotha nightclub in Cannes on Saturday night
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.
However, once they noticed they were being pH๏τographed, both Barbara and Lewis seemed very shy and looked like they did not want to be seen too closely.
Together, the duo were attending a live performance by musician Chris Brown, who was later making an appearance.
