Pop star Nick Lachey is planning to wed again - Jessica Simpson's ex-husband has asked longtime girlfriend Vanessa Minnillo to marry him.

Representatives for the couple have confirmed they are engaged.

A joint statement issued to UsMagazine.com reads, "We're excited and incredibly happy about our engagement and we look forward to a wonderful future together."

The couple started dating in 2006 shortly after Lachey divorced Simpson.

The engagement news comes just days before the couple celebrates joint birthdays - Lachey will turn 37 and Minnillo 30 on November 9.
