JOE Jackson raised eyebrows by bringing a curvy new recording artist he manages as his date to the VMAs on the night honoring his son, Michael. Jackson arrived at Radio City Music Hall with a singer known as Taina. But Jennifer Lopez was not amused when Jackson introduced her to his date, who was wearing an eye-popping dress. As they took their seats, J.Lo was spotted giving Marc Anthony a look as if to say: “What is Joe doing?” Other guests at the awards said they were surprised Jackson chose to bring the busty singer rather than wife Catherine to see Janet‘s tribute performance to his son. One said: “It was a night to honor Michael. Some people thought it was strange he brought a singer as his date. There’s a time to work the media, and there’s a time to stay quiet and respectful.”
