Houston, 43, was escorted to a benefit for juvenile diabetes research in Beverly Hills, Calif., by her longtime record producer, Clive Davis, People magazine reported Monday on its website.

"I feel great," Houston was quoted as saying, while Davis, one of Saturday evening's honorees, told People: "We're going to make a killer album."

A blond Houston, wearing a black gown and diamond earrings, sat at the main table for the 17th Carousel of Hope Ball with Halle Berry and Berry's boyfriend, model Gabriel Aubry, People said.

"American Idol" runner-up Katharine McPhee sang Houston's "I Have Nothing" at the event.

"It's her first big appearance since the breakup," McPhee, 22, was quoted as saying on the arrivals carpet. "I would love to sing with her, but unfortunately all eyes are on me."

Let's pray for Whitney that she stays clean so she can testify about her ordeal.
