There's no doubt Madonna is probably a pretty cool mom. But is she a little too laid back when it comes to disciplining her kids?

That's what many are asking after the pop singer, 55, posted a photo on Instagram of her 13-year-old son, Rocco Ritchie, holding a large bottle of gin alongside two of his seemingly underage friends also holding liquor bottles.

"The party has just begun! Bring it! 2014," she wrote alongside the photo, which was posted Jan. 4.

The picture quickly inspired heated reactions from fans, but naturally, the Material Girl couldn't care less. "No one was drinking we were just having fun! Calm down and get a sense of humor! Don't start the year off with judgment!" she wrote.
