R+B star Mary J Blige finds married life just as stressful as being single, because she constantly fears her husband will cheat on her.

The 34-year-old singer has struggled to relax after her 2003 wedding to music mogul Kendu Isaacs, despite being certain of their love for each other.

And Blige makes sure her spouse knows he is dicing with death, should he look at another woman.

She says, "I wasn't happy when I got married! I was scared. The only thing I could think about was, 'This dude is going to cheat on me. I'm going to take this chance but this is f**ked.'

"And at the same time I'd actually made it to a point where I could say, 'I love this person and I want to marry him,' but all this stuff inside me was saying, 'I'm going to kill him! He's going to cheat on me, then I'm going to kill him.'"
