New York’s “Palestinian Power Couple” is no more: Pink Floyd legend Roger Waters, a vocal critic of Israel, has split with Palestinian journalist and author Rula Jebreal.

Waters, 73, and Jebreal, 43, had been dating for a few months earlier this year, in the aftermath of Waters’ split with his fourth wife, Laurie Durning, Page Six exclusively revealed.

Their relationship became the talk of the Hamptons — where Waters owns two homes — because both are outspoken supporters of Palestinian rights. Waters is a supporter of a boycott of Israel and has likened treatment of Palestinians to apartheid South Africa, sparking criticism from the pro-Israel lobby. Likewise, Jebreal is an articulate critic of Israel and has written three books, including “Miral” — about women caught in the crossfire of the Israeli-Palestinian conflict — which was made into a movie by her ex, the famed artist Julian Schnabel.

A source had told us of Waters and the beautiful Jebreal’s relationship, “It is the talk of the Hamptons, and some people are calling them the ‘Palestinian power couple.’ One can only imagine the pillow talk.”

But another source now tells us, “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.”

Ironically, Jebreal and Waters got to know each other after they were introduced by his ex-wife Durning and Jebreal’s now-ex-husband, biotech entrepreneur Arthur Altschul Jr.

To the shock of both their exes, they then started a relationship. “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.”

The source continued, “But after Roger split with his wife, he began an affair with Rula. Arthur found out, and their marriage ended.” Reps for both Waters and Jebreal didn’t get back to us.
