Just weeks after her ex-husband, Nick Lachey, announced his engagement to Vanessa Minnillo, Jessica Simpson told the media that she is set to marry NFL star Eric Johnson after he proposed to her last Thursday, six months after they started dating. Her rep said: “Yes, I am excited to confirm that they are engaged.” The 30-year-old singer showed off her diamond engagement ring Saturday during a photocall in Kansas while promoting her Jessica Simpson Collection fashion line. Jessica previously hinted she wanted to marry Eric, 31, and have children with him. She said recently: “I am from the south so I’ve definitely dreamed of being married my whole life and having children, so hopefully that’s in my future.”
