Rihanna ‘pix’ on Queen Liz

Rihanna took a poke at Queen Elizabeth on Her Majesty’s 91st-birthday weekend, posting Instagram pix of the monarch’s head superimposed on the sexy singer’s body.

In one image, the queen’s head, complete with a scowling expression, was pasted on Rihanna’s body as the star strutted down the street wearing a brightgreen outfit and kinky, thigh-high green boots.

“Be humble,” Rihanna wrote under the image, which she posted Saturday.

Another photo (above) featured the monarch’s head on Rihanna’s body, wearing a tweed blazer and matching skirt, posing with a 40-ounce bottle of beer in a store.

The posts were a hit with many of Rihanna’s 52 million followers, but some were offended.

“This is SO disrespectful! Do not ask for respect when don’t give any,” wrote hek24.
