Did Jessica Pay For Her Ring?

Jessica, who upstaged her ex-husbands engagement moment may be having a moment of her own not to be shared. Jessica is sporting a beautiful $100 K ruby-and-diamond engagement ring.

Every woman dreams of the day she is proposed to, he surprises her with a ring.... Ok I'm living in the Ice Age. It's rumored she purchased the ring for herself. Her fiance is not working and people are asking how could he afford such a ring?  This story sounds familiar, remember Bobby and Whitney. If Jessica did purchase her own ring I guess it is no ones business but hers.
