Pop star Nick Lachey will have to pluck up courage and propose to his girlfriend Vanessa Minnillo if he wants to spend his life with the TV presenter-turned-actress - because she's too traditional to pop the question.

Insiders claim Minnillo is ready to become Lachey's second wife, but she would never follow Hollywood trends and ask her man to wed her.

She says, "I know that a lot of girls nowadays are proposing to guys, but I think I'll be old-fashioned. I'll be old and grey before I propose."
