Reverend Bob Harrington has singled the girls out for criticism because their father and manager, Joe, was once a Baptist preacher himself

"They don't represent American standards and certainly not Christian standards," cries the Texan minister.

"Their father has replaced his faith in the Lord with the love of money, which is the root of all evil. He has replaced holiness with horniness.

"[Jessica and Ashlee] will reap the dismal crops they are sowing. Their breasts will sag and their faces will wither and they will be left with nothing but a hollow shell."

Sources say the singers have lost many of their Christian fans in the US because of Jess's divorce and Ashlee's recent sexy makeover.

"Marketing Jessica as a sex kitten was all Joe's idea and it's backfired," notes an insider. "And Ashlee is going down the same road. Joe's marketing plan was simple — sex sells.

"But it looks like they've lost a lucrative segment of their record buyers along the way."
