The new Us Weekly reports that Kate Hudson has been trying to make New York Yankee Alex Rodriguez less of an egomaniac.

It must not be easy.

A former Rodriguez fling remembers seeing portraits of the slugger, 34, as a centaur hanging over his bed.

"He was so vain," his ex tells Us Weekly. "He had not one, but two painted portraits of himself as a centaur. You know, the half man, half horse figure?"

Adds the ex, "It was ridiculous."

Us Weekly also reports that Hudson, 30 — who has been front and center at his baseball games since they began dating this past spring — has been bragging to pals about what a good lover Rodriguez is.

"They love sex!" a pal tells Us Weekly of the pair who began dating in May. "They talk about it all day. Kate gets graphic talking about his body, even to her parents."
