Beyonce Knowles has finally confirmed she's a married woman - seven months after she and rap mogul Jay-Z exchanged vows in a top secret New York ceremony.

Appearing on Oprah on Thursday, the sexy star admitted it was difficult not to talk about her nuptials - because it was such an exciting day.

She said, "It's difficult because I had to really learn how to have boundaries... and balance. It's something that I never have really talked about... It was difficult and it still is because I'm so excited about it, but it's important that I keep things that are pure and real in perspective, and I keep it separate from my performance life.

"It (wedding) was very private... Outside it was paparazzi madness and inside it was really beautiful."

And she loves being someone's wife.

She added, "It feels great... The most important thing is to make sure you have your own life before you're someone else's wife."
