Beyonce Knowles believes she has a happy marriage because they try to keep it as private as possible.
The 'Halo' singer married hip-hop superstar Jay-Z in a secret ceremony in 2008 but both are reluctant to speak about their home life because they think it will add extra pressure.
She said: "Jay and I have always been very discreet when it comes to our relationship. Even after we got married nothing changed about that. I think that saved us a lot of trouble."
The 28-year-old beauty - who publicly thanked her spouse when she won a record six Grammys at last month's ceremony - also revealed she was initially "scared" when she was regarded as a role model for young women but is now embracing it.
She told Germany's FHM magazine: "The thought scared me at first. But now I think my music is more than just performing, dancing and shooting videos. I try to show women that we need to be there for each other and support each other and that you have to work to reach your goals."
But one thing still worries Beyonce - falling over on stage.
She said: "The only thing I really worry about is falling over! I always perform in high heels and sometimes the choreography is really exhausting and complicated."
