The National Enquirer has this to say…believe it if you want…

“Vanessa Minnillo has hit Nick Lachey with a wedding ultimatum – marry me by next year without a prenup or I’m gone! ‘Vanessa loves Nick, but she’s prepared to walk if he’s not willing to marry her,’ an insider told The ENQUIRER. ‘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.’ Ex-boy band member Nick, 33, and the 26-year-old beauty are spending time between homes in Los Angeles and New York – and are nearly ready to seal the deal, say sources.

“As the Enquirer recently revealed, Vanessa has picked out an engagement ring – a platinum band with a large emerald-cut diamond in the center and two smaller emerald-cut stone on each side. She first spotted the sparkler at the Kentucky Derby in May. ‘But all bets are off in Nick forces a prenup on her,’ said the insider.”
