Nick and Vanessa: 10 Carat Engagement Ring?

Nick Lachey and Vanessa Minnillo ready to get engaged?

They're not engaged yet, but when Nick does pop the question Vanessa wants a ten carat rock.

Sure, you never know if Vanessa Minnillo and Nick Lachey are together. Rumors constantly seem to swirl that these two are on the rocks or fighting, fighting and more fighting. But Vanessa made it very clear to Robin Leach while hanging out  in Las Vegas that she and her man are still very much an item—and wedding bells could be in their future. "There will always be rumblings and rumors that we've broken up," she said. "But in fact, it's very much still on—and it keeps getting better."

And will Nick take a trip down the aisle with Vanessa? She was in Vegas alone because Nick had to attend a friend's 40th birthday party. She joked, "once again I'm always the bridesmaid but never the bride." Okay, but seriously, will Nick commit? It's looking likely, but only if Nick can give Vanessa the rock she desires. Pointing to a five carat ring on the middle finger of her all-important left hand, Vanessa said that it would be "ten carats" when it moved to the "fourth finger."

We'll keep an eye out for the big ring to arrive and of course can't help but wonder what Jessica Simpson thinks of all this wedding talk! Maybe Jessica and her beau Tony Romo are next?
