Pink Floyd legend Roger Waters, a vocal critic of Israel, is dating Palestinian journalist and author Rula Jebreal after divorcing his fourth wife.

Waters, 72, and Jebreal, 43, have been dating for a few months, in the aftermath of Waters’ split with wife Laurie Durning, Page Six can exclusively reveal.

Jebreal and Waters were introduced around five years ago by Durning and Jebreal’s husband, biotech entrepreneur Arthur Altschul Jr., from whom she is now separated.

A source told us, “Arthur and Laurie are longtime friends, and they introduced Rula and Roger a few years ago. 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. Roger and Rula have been together around three months and they discuss Palestine all the time, they are both so very passionate about it.

“It is the talk of the Hamptons, and some people are calling them the ‘Palestinian power couple.’ But it is very weird for their former spouses, who introduced them,” the source added.

Waters — who has homes in Sag Harbor and Bridgehampton — is a supporter of a boycott of Israel over the issue of Palestinian rights. He has likened Israeli 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 Julian Schnabel.

Jebreal and Altschul, who married in 2013, said in a joint statement, “We’ve been separated for several months and we are working on our divorce amicably behind closed doors.” When contacted by phone, Jebreal added: “I will not comment on my personal life . . . It is not anybody’s business.” Waters’ rep declined to comment.
