How did Leonardo DiCaprio get a nosebleed?

Answer 1

Aretha Wilson slashed him in the face with a beer bottle. It cut his left temple, gave him a black eye, broke his nose so bad that he had to have a plastic surgery and his nose was bleeding.

Answer 2

Yes. If his nose was fractured bad enough that he had to get a plastic surgery, his nose had to be bloody. He also had a cut on his temple that required stitches and a black eye.
