Kate Hudson & Nick Jonas: Whole Latte Love on the Slopes

Kate Hudson and Nick Jonas are still snuggling up to each other -- this time in a California ski town with their lattes.

They were hanging together Monday at a Starbucks at Mammoth Mountain ski resort in central Cali.

The last time they were seen together was in NYC in October ... so looks like they're still going strong, but still keeping it kinda down-low.
