On February 14, the monogamists of the world will wear their hearts on their sleeves, but we'd bet a pretty penny that Emma Roberts will wear hers around her neck too. The Adult World actress, who recently became engaged to her co-star Evan Peters, stepped out for a romantic couple's dinner in West Hollywood wearing a whimsical heart necklace by Cali jeweler Maya Brenner. What we assume has to be a gift from her beau, the sterling silver strand comes on a 22-inch chain that hangs just low enough so it's perfect for layering over other delicate pieces. The long length also toughens up the heart motif. "I wanted to take what's traditionally a very feminine shape and give it a little edge, so I made the heart larger and the length of the necklace longer," Brenner told InStyle.com. If you want to steal Emma's style (or prod your boyfriend to do it for you), then shop her charming neckpiece for $180 at mayabrenner.com. Or, if you're feeling extra romantic, cop the same one in 14kt yellow gold for $600. We <3 both.
