Melissa Joan Hart Instagram – Let me explain…. While I’m proud of my performance in my most recent movie #WouldYouKillForMe, I couldn’t be more flattered that people don’t think of me as a grandmother (no matter how possible it is at the age of 47). It’s also refreshing to go viral for my work and not something controversial. I guess now Clarissa can Explain AARP or play the Middle-Aged Witch.
