Amber Heard Engagement Ring

Johnny Depp talks about the ring in David Letterman []

On the Late Show with David Letterman, Depp admitted he's wearing a female engagement ring.

Depp joked that "it's a big fallacy" that people know each other's ring size without asking, which is why he's now wearing the ring he gave to Amber.

Why didn't he return it instead? "I put it on," he said. "She has the other one that fits."
