The funny lady confirmed the nickname but admitted that she never thought it would follow her for so long.
"When that nickname came up, I thought, 'Certainly this won't stick 15 years later,'" McCarthy said. "Somehow I am 'The Mooch,' and now other friends call me that too."
The nickname is all out of love, of course, as the couple makes such a perfect pair that they frequently work together. They co-starred in 2011's Bridesmaids and co-wrote and acted together in 2014's Tammy, plus they both co-wrote the upcoming film, The Boss, along with writer Steve Mallory.
McCarthy headlines The Boss, which is directed by Falcone, as a titan of industry who is sent to prison after she's busted for insider trading. When she's released, it's back to the drawing board to come up with a business scheme that will put her back on top.
