Heidi, Mariah and Michael J. Fox were all on hand for the opening night of the Muhammad Ali Exhibition in NYC this week. The exhibition's proceeds will go towards the Michael J Fox Foundation for Parkinson's which Ali suffers from as well. Mariah came out of nowhere last week but she's back and she's even sporting the shades indoors. Not sure if that's really necessary but all that really matters is that they raised lots of cash for this good cause!
