Halle Berry headed back to her car after stopping by a friend's house in Studio City, CA, yesterday. Halle's huge emerald ring was on display as she held out her left hand. Her fiancé, Olivier Martinez, confirmed their engagement earlier this month, after speculation about their new relationship status began in January. Halle and Olivier got close while filming Dark Tide in South Africa over the Summer in 2010, and they'll soon get back to working together when they start promoting the movie ahead of its DVD release in April. They've also apparently been looking into a move to Olivier's native Paris, since Halle was seen scoping out schools for her daughter, Nahla, last week.
