Halle Berry showed off her 5-month-old daughter at a trip to the Los Angeles Zoo on Saturday — and wore a mysterious ring on her finger.

Nahla Ariela Aubry, 42-year-old Berry's daughter with model boyfriend Gabriel Aubry, 31, smiled, danced and took a nap on her mom's shoulder at the zoo.

The baby has been seen in public before — but only from behind. Berry threatened to press charges against a paparazzo who photographed the actress with her daughter in the family's backyard in July.

And although she's sworn she'll never marry again, Berry was photographed wearing a sparkling band on her wedding-ring finger on Friday and Saturday.

"I never want to be married again," the twice-wed actress said on "Oprah" in October 2007. "I guess you could say I have bad taste in men. But I no longer feel the need to be someone's wife. I don't feel like I need to be validated by being in a marriage."

Berry and Aubry have been a couple for three years. They met in 2005 at a Versace photo shoot.
