Former beauty queen Lizzie Arnold is refusing to become involved in a serious relationship with Nick Lachey because he is still married to Jessica Simpson. The 26-year-old Arnold and singer speak on the phone "virtually every day", but she has doubts about the future of their relationship.

She says, "We're good friends, but I don't know exactly where this is going. He's going through a tough time and we're there for each other. But I don't feel comfortable getting serious with a married man."

The former Miss Kentucky insists she's not in the market for a serious relationship. A friend of Arnold's says she is proceeding with caution adding, "She won't get serious with him until he is divorced."
