Liv: Kiss Me Kate!

Kate Bosworth was spotted at Sant Ambroeus cafe in the West Village -- getting majorly smooched by Liv Tyler!


Liv was lunching with "Smother" co-star Dax Shepard, and Kate was munching with supermodel Helena Christensen, when Liv and Kate bumped into each other and -- got reacquainted with this hot liplock!

Mwwwwwaaaaah!
