Looks like Taylor Swift
will have some fresh material for her next album!
The pop star, 22, and beau Conor Kennedy, 18, are over, sources confirm to PEOPLE.
The pair, who enjoyed a whirlwind summer romance
frolicking through Hyannis Port, Mass., showing several
public displays of affection
, split a while ago.
"His friends have said it's over," says a source at his school, the Deerfield Academy, adding, "I have the feeling she ended it."
It's a bummer since Swift even got the stamp of approval
from Conor's grandma, Ethel Kennedy, who called the starlet, "spectacular."
In August, a source told PEOPLE
Swift was "swept off her feet" by her then-boyfriend.
But Swift's busy schedule could have made things difficult. She's currently promoting her new album, Red
, performing at the Country Music Awards Thursday, will co-host the Grammy nomination concert, and just announced a 2013 tour.
