Leonardo DiCaprio's lively raising the bar again.
The duo was also seen last week in Cannes, France, looking quite lovey-dovey on a yachting trip.
A source told Grazia magazine: “Blake is exactly Leo's type. He likes leggy blondes with big smiles, and Blake fits the bill perfectly.
“Leo and Bar have been through some rocky times recently and Leo is famously reluctant to settle down. The rumors around Blake and Leo won't go away.”
DiCaprio, 36, had been on- and off- again with Refaeli, 25, since breaking up with another high-profile beauty, Gisele Bundchen, in 2005.
