Actor Leonardo DiCaprio appeared to be wearing a heart monitor as he walked through the streets of New York City.

In the photos obtained by TMZ, the 42-year-old Oscar-winner was seen wearing a round suction cup on his left chest.

The actor was spotted the other day with the same suction cup, which seems to be attached to his skin.

Meanwhile, DiCaprio is reuniting with Martin Scorsese in an upcoming true-crime thriller, based on the bestselling book by David Grann, "Killers of the Flower Moon: The Osage Murders and the Birth of the FBI".
