LOS ANGELES, US - Pop star Britney Spears releases a music video on Wednesday that features the troubled singer as an animated superhero in a futuristic world.

The music video will premiere on Wednesday on dedicated Web site (www.BlackoutBall.com) at 6:30 p.m. EDT and accompanies her latest single "Break The Ice" -- the third from her 2007 album "Blackout."

The release of the video, along with an upcoming acting role on U.S. television comedy "How I Met Your Mother," marks something of a comeback for Spears, 26, whose career has been sidelined by psychiatric problems and months of bitter child custody battles.

Spears' Jive record company said the video was made in South Korea in Japanese anime style. Spears last year released two singles from the "Blackout" album which has sold more than 2 million copies worldwide but whose commercial success pales in comparison to the singer's heyday six years ago.

In the past year, Spears has been in rehab, lost custody of her sons to ex-husband Kevin Federline and been hospitalized twice for psychiatric evaluation.

Management of her personal and business affairs have now been handed over by court order to her father.

Television executives said on Monday that Spears had been cast in an episode of "How I Met Your Mother." The episode is expected to air on March 24 and according to insiders Spears will play a receptionist in a doctor's office.

Spears got her first role in a prime-time U.S. television series in March 2006 when she played a Christian conservative talk show host in a guest appearance on "Will & Grace." --REUTERS
