Beyonce Knowles is "terrified, but excited" about married life.

The 'Single Ladies (Put a Ring on It)' singer — who wed Jay-Z earlier this year — said it is taking time for her to get used to her new relationship status.

She said: "This is a new chapter for me. I’m terrified, but excited. It’s like I’m a new woman!"

The 27-year-old beauty said Jay-Z has inspired a lot of songs on her new record 'I Am…', adding: "I am happy right now and this album has a lot of love songs that talk about my emotions — me naked with my heart exposed."

Knowles also spoke about her role as blues singer Etta James in upcoming film 'Cadillac Records', a role for which she was required to gain 15lbs.

She told InStyle magazine: "It was way easier — and tastier — than having to lose so much weight for 'Dreamgirls'. I also studied Etta's mannerisms and tried to make them my own. My performance, my posture — everything was so different from who I am. It was difficult."
