No sad songs for Whitney

Whitney Houston is so happy, she has refused to record any sad songs for her comeback album, according to collaborator Ne-Yo.

The singer has not released a record since her 2003 Christmas offering, 'One Wish: The Holiday Album'. Her last original studio album was 'Just Whitney', released the same year.

The vocal superstar is currently working on an album to relaunch her career, which is expected to hit stores later this year.

R&B star Ne-Yo, who has been helping the star put her new album together, insists it will not feature any downbeat ballads - because of the improvement in Houston's personal life.

"People are expecting something fantastic and I think they are going to get it," he said.

"Whitney doesn't want any sad songs on this record. She isn't going for tear jerkers. She's happy raising her children and wants her music to reflect that. It's already sounding great."

Houston endured a messy public divorce in 2007 when she split with her husband of 15 years, Bobby Brown, as well as battling a string of alleged drug problems.

Houston has full custody of the former couple's 15-year-old daughter, Bobbi Kristina.
