Fresh into his relationship with Taylor Swift, has Conor Kennedy already joined the ranks of her famous ex-boyfriends – including John Mayer, Taylor Lautner and Joe Jonas – whose memories with the country crooner play out in her music?
Not so fast, according to one source, who says this love song is still being written, with Swift falling hard for the son of Robert Kennedy Jr. and the late Mary Kennedy.
“They have been dating for a bit,” says the source. “She is swept off her feet.”
Age is clearly not a factor – he’s 18 and she’s 22 – but what may be is the Grammy winner’s affection for his extended family. Even before they were spotted getting cozy, Swift made no secret of her fascination with the Kennedys.
