Former TRL VJ Vanessa Minnillo has ordered BF Nick Lachey to marry her-sans prenup-by 2008 or hit the road.

‘Vanessa loves Nick, but she’s prepared to walk if he’s not willing to marry her,’ says a National Enquirer mole.

‘And she’s not going to get involved in a prenuptial agreement. She feels marriage is forever, and she doesn’t want to begin a lifelong commitment by signing an agreement that’s just an out for a divorce.’

Van has already selected an engagement ring; a large emerald-cut diamond accentuated by two smaller emerald-cut stones on the side.

‘With Vanessa’s ultimatum, it’s going to come down to love or money for Nick.’
