Whitney Houston has been on a date with a singer almost half her age.

The 43-year-old star was seen leaving Beverly Hills restaurant Maestro on Sunday night (14.01.07) with Ray J, the younger brother of singer Brandy, who turns 25 today.

A source told gossip website X17online: "They looked like they'd had an enjoyable evening, but they weren't happy to be pictured together.

"Ray helped Whitney into his car and drove her home."

Whitney filed for divorce from bad boy husband Bobby Brown in September last year.

Whitney, 43, and Bobby, 39, tied the knot in the grounds of her five-acre, US$11 million mansion in New Jersey on July 18, 1992.

The split came just months after it was alleged Whitney, who has a 13-year-old daughter, Bobbi Kristina, with Bobby, was addicted to crack cocaine and living in squalor.
