Wedding ring on the cards for Nicole Richie

Nicole Richie and Joel Madden are to marry, but the couple have not decided on when they will be heading down the aisle.

Nicole Richie may soon be seen sporting a wedding ring after she confirmed she and boyfriend Joel Madden are to marry.

Speaking on US television show The View as part of a promotional tour for her new book, Richie revealed the couple will tie the knot, but haven't yet settled on a date, the Daily Mail reports.

"We feel that it's the right time. We're ready – and it's something that feels great," she remarked, adding her and Madden "haven't planned anything" yet but will "find a time" to head down the aisle.

The 29 year-old, who has two young children with the star of rock band Good Charlotte, wore four different outfits in one day as she worked to promote Priceless, her second novel.

Reese Witherspoon may soon be following Richie and Madden down the aisle, after her boyfriend Jim Toth was reportedly spotted shopping for a diamond engagement ring in Hollywood earlier this month.
