After a sailing trip the following day, "Conor put his arm around Taylor and they kissed behind the boat shed," another onlooker says.
"Taylor is officially dating Conor Kennedy," a source confirms to Us Weekly.
(Swift was previously linked to Conor's cousin Patrick Schwarzenegger after she was photographed hanging with the model with the Kennedys on July 4.) It has been a tragic, tumultuous time for young Conor, whose troubled mom Mary Kennedy hung herself in the family's estate in Bedford, New York in May.
When asked about the possibility of welcoming Swift into the family in August, Ethel responded, "We should be so lucky." A report by Radar Online claims that the young couple may have split because Swift was putting too much pressure on the relationship.
"Taylor is obsessed with the Kennedys and was living out a fairytale with Conor," a source told the gossip site. Earlier this week, Swift debuted her new album, "Red," chock full of songs about her past exes - a collection of Hollywood men that includes Joe Jonas, John Mayer and Jake Gyllenhaal.
"They quietly parted ways a while ago," the pal told the magazine. "It's been over a month since they've even seen each other," the source continued.
"With her promotion for 'Red,' she has no time off until the end of the year."

Well, wouldn't you know, it's been reported that the blonde starlet not only sported one of her go-to dresses, but she's also the subject of another rumored romance. As we all know, when Swift settles down, it's not with any fella — she only dates top-tier dudes (Jake Gyllenhaal, John Mayer, Taylor Lautner, etc.).
