Billy Joel is continuing to move on up in Sagaponack. We just found out that he has spent $11.6 million buying the house next door to his $16.75 million house in Sagaponack that he just bought off of Roy Schieder last year. Looks like him and Katie Lee have a lot to be happy about. This year, his concerts have been more in demand and he also just debuted his new song, “Christmas in Fallujah,” at the Sears Centre in Hoffman Estates outside of Chicago. The song was inspired by letters he received from soldiers in Iraq and has been a hot topic since he chose to have Cass Dillon sing the song, who is an up and coming star. His new 16.75 million dollar place is a three bedroom and two bathroom with one hell of a view.
