Roger Waters has split from Rula Jebreal.
The Pink Floyd star, 73, reportedly started dating the 43-year-old journalist a few months ago following his split from fourth wife Laurie Durning last year, but the pair have now gone their separate ways and it was said their families "didn't get along".
A source said: "It was over as quickly as it began - while they agreed on many issues, they couldn't find common ground on others. Plus, their families didn't get along."
Roger and Rula were dubbed the "Palestinian power couple" because they were both outspoken about rights in Palestine.
A source added: "It is the talk of the Hamptons, and some people are calling them the 'Palestinian power couple.' One can only imagine the pillow talk."
The couple got together after being introduced by their exes, Laurie, and Rula's now former husband, entrepreneur Arthur Altschul Jr.
A source added to the New York Post's Page Six column: "It was very weird for their former spouses, who introduced them.
"Rula had asked to meet Roger because he's a vocal activist for Palestine. The two former couples have had dinner together many times. They were all friends."
Roger and Laurie got engaged in 2004 and married in January 2012 before filing for divorce in September 2015.
He was previously wed to Priscilla Phillips - who he has a son, Jack, 32, with - for eight years from 1993 to 2001, and before that Lady Carolyne Christie, who he has son Harry, 39, and daughter India, 38, with.
Roger and Carolyne divorced in 1992 after 16 years of marriage.
His first wife was childhood sweetheart Judy Trim, who he tied the knot to in 1969 before divorcing in 1975.
They had no children together and she sadly died in 2001.
