Whitney Houston and Bobby Brown have had a stormy relationship

"I'm really looking forward to that," Brown said before a tribute concert to the late Paul Robeson in New York this week.

"She's making me sing and I'm making her dance, so it's a beautiful combination."

Whitney Houston recently avoided prosecution for alleged drugs possesion.

Houston's bag was seized in January at an airport in Hawaii, allegedly containing marijuana in a plastic bag.

A judge ruled the case dismissed and her record cleared of the petty misdemeanor in three months, if she agreed to several probation-type conditions.

Among the conditions was a $3,000 (�2,100) donation to a youth-oriented anti-drug programme on the island.

I'm a better-built brother, most definitely

Bobby Brown

Bobby Brown, who spent two months in a Florida jail this year for violating his parole on a drink driving conviction, claims he is a changed man.

"I have to do things that are different now," he said.

"Since my life is different, my days are different, I have to do something different.

He added: "I'm a better-built brother, most definitely."

The couple have not given any details about the possible tour, such as venues or dates.
