Taylor Swift is dating Conor Kennedy, the 18-year-old son of Robert Kennedy Jr. and the late Mary Kennedy.
It was previously thought that 22 year-old Swift was dating Kennedy's cousin Patrick Schwarzenegger when she was spotted spending Independence Day with him and some of the other Kennedy family members, but she spent last weekend with Conor.
On July 25, Swift and Kennedy were photographed eating pizza in a restaurant in his hometown of Mount Kisco, where they "walked out hand and hand," according to a source.
The Love Story singer - who has previously dated John Mayer, Joe Jonas and Jake Gyllenhaal - also attended church with several members of the Kennedy family on Sunday.
Swift spoke of her fascination with the Kennedys in an interview in Vogue magazine in February, in which she also declared she would never keep her love life under wraps.
Kennedy has had a difficult time recently after his mother Mary died on May 16 amid a bitter divorce from Robert Kennedy.
Conor Kennedy recently applied to be named administrator of his mother's estate, a request his father had no objections to.
It was revealed last week that Swift's Merrill Lynch financial adviser father Scott and homemaker mother Andrea - who were married for almost 25 years - have also split up.
Swifts fourth studio album is due out in October.
