The ‘Titanic’ star was recently spotted leaving London’s Groucho Club – hand firmly in hand with Burberry model lover Louis Dowler.
The touching scene continued as the pair, both 34, were driven to Mahiki nightclub in Mayfair, clasping fingers and giggling on the back seat.
Winslet has kept a low profile since splitting from 44-year-old film director Mendes in March.
“Kate and Louis are really happy together – and they’re far more relaxed now that everyone knows they are a couple,” News of the World quoted a pal as saying. (ANI)
