If there's one thing Madonna
knows a thing or two about, it's controversy.
The pop star, 55, posted a photo
of her son Rocco
, 13, and his seemingly underage friends posing with bottles of gin and vodka to her Instagram on Saturday.
"The party has just begun! Bring it! 2014," she wrote.
Some fans, however, weren't feeling the Material Girl's idea of "bring it."
"Having under age kids pose with booze is aweful [sic]. I'm a big fan too :(" one reader wrote.
Madonna, who pops up in several of her son's pictures on his Instagram account
, was unfazed by the reactions. The singer's message to her critics is to chill out.
"No one was drinking we were just having fun! Calm down and get a sense of humor! Don't start the year off with judgement!" she wrote.
