BEIJING, Nov. 1 (Xinhuanet) -- Britney Spears, during a seven-minute interview with a morning talk show host in Los Angeles, defended her role as a parent and said "how cruel our world can be" in reference to critics of her lifestyle.

Spears also talked about her new album "Blackout" during the interview with "American Idol" host Ryan Seacrest, who has a morning radio show on KIIS-FM. She often giggled as her assistant, Alli Sims, and friend, Sam Lufti, shouted and laughed in the background.

When Seacrest asked Spears if she was doing all she could for her children, Spears replied, "Oh, God, yeah."

"People say what they want and do what they do and it's sad how people, how cruel our world can be," she said. "At the end of the day ... you've just got to know in your heart that you're doing the best you can and that's basically it."

Spears was unclear when Seacrest asked how often she would see the boys.

"That's, like, all in the court," she said. "Stuff like that, my lawyers know all that stuff."

Spears’"Blackout," her first studio album in four years, was released Tuesday. Besides a video for "Gimme More" and a widely panned performance at the MTV Video Music Awards, she hasn't promoted the record.

Spears said she didn't do anything special to celebrate the release ─ "we watched movies ... had fried chicken."
