Eminem worries he will become an embarrassment to his daughters.

The 'We Made You' hitmaker - who raises his 14-year-old child Hailie, 17-year-old adopted niece Alaina and former wife Kim's seven-year-old girl Whitney - admits it is growing increasingly different to show his love for the trio as they get older.

He said: "It's a catch-22: I want to, as a father, express my love for my girls, but I don't want to go too far with it, where it becomes a hindrance in their lives. When they were younger... it was easier."

The 37-year-old star - whose records have infamously mocked other people in the public eye - has previously battled an addiction to prescription drugs and admits his problems started when he "ran out" of enemies to target.

He explained to Spin magazine: "I was trapped in my head. I'd spent most of my career going against the grain. Calling bulls**t. And suddenly, I started running out of enemies.

"I started to become that cliche - my own worst enemy."

The Detroit-born star also revealed he sometimes goes back to the poverty-stricken neighborhood where he grew up to remind himself of how far he has come in life.

He said: "It may sound corny, but I'll go by and try to remember how things were when I was in those houses.

"I'll go back and remember, like, f**k, man, how life was back then. How much of a struggle it was. As time goes by, you might get content and forget things."
