Vanessa Minnillo Yearns for Marriage, Enormous Engagement Ring

She might not be shopping for her own engagement ring, like Kim Kardashian.

But Vanessa Minnillo is already making plans for one.

In an interview with journalist columnist Robin Leach, the longtime girlfriend of Nick Lachey pointed to a 5-carat ring and said:

"It will be 10 carats when it moves to the fourth finger!"

Minnillo was laughing when she said it... but 10 carats?!? Such a piece of jewelery would weigh more than the breasts of Lachey's ex-wife, Jessica Simpson.

Overall, the former MTV VJ assures her two dozen fans that the "romance is still going strong. There will always be rumblings and rumors that we've broken up, but in fact, it's very much still on – and it keeps on getting better."

Hey, Vanessa, remember when you were caught on camera being railed by your boyfriend? That was funny.
