Jazz star Harry Connick Jr has revived focus on Jennifer Lopez's shapely bottom, after singing its praises recently.

Thrice-wed Lopez has successfully managed to steer attention away from her much-celebrated asset recently, but musician Connick Jr admits he couldn't look away when he laid eyes on her buttocks.

He says, "(I) am telling you, when you see her from the back you just... it's like eating too much pecan pie... Everything slows down and you can't respond to people."
