Taylor Swift is now rumored to be dating Conor Kennedy, the 18-year-old grandson of the late Robert F. Kennedy and son of Mary Kennedy, who tragically committed suicide in May.

A witness who saw the pair loved up together, told the New York Post that the two were canoodling at the Kennedy compound in Hyannis Port, Mass., last weekend. They allegedly jumped on a trampoline and held hands at a beach after attending a house party. They later joined friends at a pizzeria and also reportedly attended a church service together on Sunday.

Just earlier this month, there were reports that the the country music star was dating Patrick Schwarzenegger, after she was pictured attending a 4th of July party at the Kennedy compound.

They were spotted enjoying several activities together including taking a stroll on the beach alone, hanging out at the Kennedy Compound with several members of the Kennedy family, sailing on Ted Kennedy Jr.'s boat Mya, attending the annual Fourth of July parade and playing Capture the Flag with several Kennedy grandchildren.

Patrick, who now calls himself Patrick Shriver on Twitter, had tweeted, "Had such an amazing day. Best 4th of July I could ask for. Hope everyone had a great day!"

Ethel Kennedy's granddaughter Kerry Townsend tweeted, "Arrived at my Grandma's house to find her chilling with Taylor Swift and Dianna Agron. I hope I'm this cool when I'm 83!"
