Taylor Swift is dating Conor Kennedy.

The 22-year-old singer is reportedly so serious about the 18-year-old son of Robert Kennedy Jr. and the late Mary Kennedy that she has put in an offer on a property next to the Kennedy compound in Hyannisport, Massachusetts, according to Laineygossip.com.

It was previously thought that Taylor was dating Conor's cousin Patrick Schwarzenegger when she was spotted spending Independence Day (04.07.12) with him and some of the Kennedys but she spent last weekend with Conor and was seen walking hand in hand with him.

'Love Story' Taylor - who has previously dated John Mayer, Joe Jonas and Jake Gyllenhaal - also attended church with several members of the Kennedy family on Sunday (29.07.12).

Conor has had a difficult time recently after his mother Mary hanged herself on May 16 in a barn near the family home in New York's Westchester County amid bitter divorce proceedings in which Robert won temporary custody of their four children, ages 11 to 18.

He recently applied to be named administrator of his mother's estate, a request his father had no objections to.
