MICK Jagger, father of the year? The wrinkly rocker is the proud propagator of seven children by four different women, and it’s been hard finding quality time with all his spawn. But Jagger had lunch yesterday with his youngest, Lucas, 8, at Nello’s with the boy’s mother, Brazilian lingerie model Luciana Morad. They left separately to thwart fans waiting with camera phones. Father and son climbed into a waiting car, leaving Morad behind in the restaurant. Her pregnancy was the last straw for Jerry Hall, the mother of four of Jagger’s children.
