Johnny Depp showed off a diamond engagement ring that he called a "chick's ring" on Monday -- indirectly confirming rumors of his engagement to actress Amber Heard.

While in Beijing promoting his new film "Transcendence," the 50-year-old "Pirates of the Caribbean" star was asked whether he was engaged. He replied: "The fact that I'm wearing a chick's ring on my finger is probably a dead giveaway. Not very subtle." He laughed as he lifted up his left hand and displayed a single diamond on a band around his ring finger.

His comments follow months of unconfirmed reports of his engagement to Heard, 27, who starred with Depp in "The Rum Diary" and with Kevin Costner in "3 Days to Kill," which was released in the U.S. earlier this year. In a trademark off-the-wall comment, Depp said: "I think that I would be better at making women's shoes than I would be at wedding planning, I can't plan anything. I'm really bad at that stuff."

In 2012, Depp split with his partner of 14 years, French model-singer Vanessa Paradis. They have two children.

In "Transendence," Depp plays a terminally ill scientist who downloads his mind into a computer in the sci-fi drama that asks: What if we could upload a human mind into a computer? It also stars Rebecca Hall as Depp's wife and Morgan Freeman.

"The technology that exists within the film, what I find most fascinating is that a lot of it exists already and by all accounts from scholars and professors and scientists that species of technology is not far away, that kind of artificial intelligence," said Depp in an interview.

"It's one of those films that one person is forced to make a choice in an instant, when your loved one is dying and you have a split-second decision if you have the ability to upload their consciousness into a computer, would you do that? It's quite a strange decision to make, but for love I think we would all do it."

"Transcendence" comes out on April 18 in both the U.S. and China.
