After three years and two kids together, Nicole Richie and Joel Madden have finally gotten engaged! When a fan spotted Nicole wearing a new ring on her left hand at NYC hotspot Abe & Arthur's just after 8:30 pm on Feb. 15, the fan congratulated Nicole and fiancé Joel Madden -- who both confirmed the good news. "Thank you," a beaming Nicole told the fan. Joel echoed the thanks as well. A friend of Nicole's tells Life & Style, "she's beyond thrilled and so excited to start planning her dream wedding."
