"When in Rome, do as the Romans do," the saying goes. And Kim Kardashian concurs:

Kardashian and beau Kanye West took a Roman holiday this week, presumably in honor of her 32nd birthday Sunday, and the pair packed on the PDA in the Eternal City.

Kardashian and West haven't been shy about showing affection in public. Just last week, the couple shared an intimate moment while house hunting in Miami.

Though Kimye spent some time apart last month when Kanye attended Paris Fashion Week sans Kim, Kardashian is glad West is back by her side to advise on sartorial matters. "Why do I always dress cooler when my bf is in town!?" she tweeted.

Kim and Kanye steal a smooch:
