The pair have only been dating for a few months but it was an intense relationship with the country singer finally entrenched in the Kennedy family which brought her great delight because she's obsessed with the dynasty.
And hopes that this was the beginning of a new generation of the political family immersed with showbiz royalty has now been dashed.
"They quietly parted ways a while ago," a friend told Us. "It was just a distance thing. No hard feelings. They're fine."
Taylor and the high school senior were first seen at the Kennedy family compound in Hyannisport, MA, back in July. The 18-year-old was grieving the loss of his mother Mary Richardson Kennedy who had committed suicide just two months prior.
"It's been over a month since they've even seen each other," the friend added. "With her promotion for Red, she has no time off until the end of the year."
Earlier this summer, Taylor had even chartered a private jet to collect her beau so they could spend some time together after spending a week apart.
Taylor has quite the list of former boyfriends which include Taylor Lautner, John Mayer, Joe Jonas, Jake Gyllenhaal and Harry Styles.
She appeared on Ellen this week where she said that she felt "so bad about myself" because she was always associated with different guys.
