For one thing, she disapproves of Affleck's huge back tattoo of a Phoenix.
"It's awful! What are you doing?" the "Shades of Blue" star, 46, told host Andy Cohen on "Watch What Happens Live" Monday. "I mean, I would tell him that. I would tell him, 'What are you doing?' It has too many colors. His tattoos always have too many colors. They shouldn't be so colorful. You know what I mean?"
Asked about her former fiancee's latest tattoo during the "Plead the Fifth" segment, Lopez added, "They should be cooler."
Lopez isn't the only one to bash Affleck's back tattoo.
"You know what we would say in my hometown about that? 'Bless his heart,'" the "Miracles From Heaven" star teased. "A phoenix rising from the ashes. Am I the ashes in this scenario?"
She then added, "I take umbrage. I refuse to be the ashes."
