Pop princess Rihanna is being slammed for “dissing” stodgy Queen Elizabeth

in a pair of goofy, Photoshopped pics she posted online.

In one, Elizabeth’s noggin was on a pic of the songbird prancing in a bright green outfit

and kinky thigh-high green boots with a caption reading, “Be humble.”

The other had the 91-year-old queen’s head on a pic of the singer in a glitzy, clinging bodysuit.

The jokey posts triggered some online outrage.

“This is SO disrespectful!” reads one post. “Do not ask for respect when you don’t give any.”

Just five months ago, the queen’s grandson Prince Harry joined the Barbadian singer

in her native country to increase awareness for HIV testing.

“Looks like RiRi forgot about that royal connection,” says a fan.
