AceShowbiz - Swifties are hearing wedding bells. Rumors swirl that Taylor Swift and her longtime boyfriend Joe Alwyn may have been secretly engaged after they enjoyed a whirlwind break in Cornwall, England.

The couple, who has been together for almost six years now, recently jetted from her Nashville home to London for a three-day getaway, according to The Sun. They reportedly flew by a private jet last week before heading to holiday hotspot St. Ives.

The fact that the pop star and the British actor travelled 4,000 miles for just a three-day visit to the town shows it was "particularly special" for the couple. "Taylor's a superstar and obviously very wealthy, so she can travel almost anywhere she wants at any time," a source tells the site. "But to go that far just for a few days clearly meant a lot to them."

The so-called insider further weighs on the pair's trip, "It feels like things are getting more serious and people think an engagement could be on the cards. That could explain such a long journey to a specific place."

As to where Taylor and Joe are in their relationship now, the source claims, "Taylor is keeping her cards close to her chest, but they're certainly very happy and enjoying their time together. Lockdown made things even more serious and they've lived together throughout."

Taylor and Joe reportedly rented a house for their romantic getaway rather than staying in a hotel for maximum privacy. After three nights, they returned to the U.S. with a 3,000-mile flight to Maine. A pal adds, "It sounds a gorgeous trip."

Taylor and Joe have been splitting their time between the U.S. and London in recent years. They share a £7million home in Primrose Hill, but the "Lover" hitmaker still considers Nashville her "main house."
