Bertinelli 'happiest when with fiancé'

Valerie Bertinelli's personal trainer Christopher Lane has said that the star is "happiest" when with her fiancé Tom Vitale.

Speaking to People, Lane revealed that the pair will be "a great married couple", but that not much will be different once vows are exchanged.

"I don't know if a whole lot is going to change. They still really like each other. They adore each other. It's not easy to mix families and they've done such a good job," Lane said.
