Rihanna vs. Selena Gomez, Joan Rivers Rant [WATCH]: 'Fashion Police' Comedian Says 'Get Off Drugs, Shut Up' About Israeli-Palestinian Conflict

According to outspoken comedienne Joan Rivers, pop starlets including Rihanna and Selena Gomez should "shut up" when it comes to world issues they really know nothing about.

Drake's 26-year-old ex and the 22-year-old "Come & Get It" songstress both recently voiced support for Palestine on Twitter in regards to the ongoing war in Gaza:

Several people were offended - including the "Fashion Police" critic.

During a recent interview with a popular news station in Israel via satellite, Rivers went on yet another heated rant:

"Selena Gomez, who just came out of rehab, who I believe is not a college girl, Rihanna, who is beautiful and not the smarted bulb in the lamp - they see pictures of children and they go crazy. They're not listening! If America were being attacked by Mexico and one rocket came over, there would not be a Mexico."

The 81-year-old actress concluded with, "These girls should shut up, and put on pretty clothes, and get themselves off of drugs."

Woah. But do Mstars readers actually agree?

Rivers later went on to "joke" about the physical appearance of Palestinian people, saying that plastic surgery will ultimately promote peace...

"Because once somebody's had a nose job, they won't fight, because they're scared the new nose will get broken... There will be peace in the Middle East."

Oh, man. And she had a lot more to say in regards to the current situation.

Surly this video will go viral soon:
