Mariah Carey was really feeling the positive vibes on St. Patrick's Day. So much so, that she got a tattoo planted on her chest. Okay, it was actually a fake tattoo of a Shamrock but it looked very good nonetheless.

Mariah posed for a quality Instagram picture showcasing her busty cleavage in all of its "milfy" glory.  Check out the sexy Mariah on St. Paddy's day above, along with more steamy pictures from the hot mama.  How are you feeling her fake ink?
