Taylor Swift and Tom Hiddleston take their hand-holding tour to Rome.

Taylor Swift and Tom Hiddleston's fast-budding romance is straight out of a dream.

After showing sweet PDA in Rhode Island, Tennessee and London, the couple continued their enviable vacation by going to Rome, Italy, on Monday, where they were spotted by fans. Clad in a cute, bright yellow sundress and blue flats, the 26-year-old singer held hands with her handsome British beau as they toured the Colosseum together.

The two were also spotted sharing a meal together, as the 35-year-old Thor star glanced at his phone.

The romantic Rome trip comes after Swift appeared to completely charm Hiddleston's mother, Diana, over the weekend, when they met in his hometown of London. The couple took Swift's private jet on Friday to spend time with the actor's family and go on beach dates, where they again showed plenty of affection towards one another.

Hiddleston has also already met Swift's parents, Andrea and Scott, a source recently told ET. Swift introduced her new beau to her mom and dad at her apartment in Nashville, Tennessee, last Thursday, the source said, only a week after the two went public with their relationship.

Last week, Swift and Hiddleston notably couldn't keep their hands off one another in Nashville. The pair wasn't shy about dancing together at Swift's bestie Selena Gomez's concert on Tuesday, and linked hands during an intimate dinner with friends on Thursday -- Hiddleston at one point kissing Swift's hand as she happily gazed at him.
