August 21, 2012 (CENTERVILLE) _ Country singer Taylor Swift joined several members of the Kennedy clan -- including boyfriend Conor Kennedy -- in a somber weekend visit to the grave of his mother in Centerville.

Swift and Kennedy held hands and at one point appeared to bow their heads in prayer while visiting the resting place of Mary Richardson Kennedy on Sunday.

The New York Daily News says Conor Kennedy also got down to clear some overgrown grass from the unmarked grave. 

Swift recently purchased a house in Hyannisport across from the Kennedy compound.

The 52-year-old Mary Kennedy hanged herself May 16^th.
