Britney Spears has criticised people for treating her unfairly during the ongoing coverage of her custody battle with former husband Kevin Federline.

Over the past month the troubled pop princess has lost custody of her children, settled one of the charges she faced in a parking offence case and met court orders regarding drug tests and parenting classes.

Spears' involvement in the two court cases and reports about her partying at nightclubs have been extensively covered by the media in the past few months.

Speaking to American Idol host Ryan Seacrest's morning radio show, the star said she was trying her best to cope with the constant attention.

Asked about the impact the coverage of her legal proceedings with Federline had on her, she said: "People say what they want and do what they do. It's sad how people ... how cruel our world can be. But at the end of the day you got to know in your heart that you are doing the best that you can."

The Baby One More Time star told the show that she was doing the best job she could in raising her two sons Sean and Jayden.

The 26-year-old singer, who is currently promoting the release of her latest album Blackout, also spoke about her new studio release. Her first single from the album, Gimme More, has been widely played on radio, television and the internet.

But Spears told Seacrest that her favourite track on the album was Heaven on Earth.

"I really like Heaven on Earth. I think it's a cool track. It's kind of different from all the other songs," she said.

The singer added that she did not celebrate the album's release in stores yesterday by going out, saying that she opted for a "laidback" time where she watched movies instead.
