Kevin Federline has criticised Nick Lachey and Jessica Simpson, saying he doesn't believe in divorce.

The wannabe rapper thinks Lachey and Simpson didn't try hard enough with their marriage, according to TeenHollywood.com.

He explained: "My situation is different. I ain't gettin' no divorce. F**k that! I don't believe in that s**t. Once you get married, you're in it for the fight...They deserve whatever they get."
