Whitney Houston is back, cousin Dionne Warwick excitedly tells People magazine. The "I Say A Little Prayer" star says Houston is back to perform even in the midst of strong allegations from ex-husband Bobby Brown.

Before her performance at Muhammad Ali's Celebrity Fight Night XIV Friday, the 67-year-old singer exclaims to the magazine, "Whitney Houston is back!"

"I'm thrilled that she's in the studio and working on her new album. No doubt she's overcoming everything that has been put in front of her even this week."

Just last week, Brown had publicly blamed Houston for influencing him to use cocaine. His autobiography, which details his relationship with his ex-wife, is due out next month.

However, the "I Have Nothing" singer refused to comment on the allegations "even if it's to set the record straight."
