Either Janet Jackson wasn’t as ill as everyone thought, or her boyfriend is a jerk. That’s what the tabloids are deducing this morning, anyway. While Jackson was being hospitalized for an undisclosed and sudden illness that prompted her to cancel a show in Montreal and two more dates in the U.S., her boyfriend, producer Jermain Dupri, was reportedly out clubbing with rapper T.I.

First, there was the report that he threw up in longtime girlfriend Janet Jackson’s lap during his birthday party at Tenjune.

And while Janet was in the hospital last night, Jermaine was seen out partying. He was spotted at Patrón’s Music in Motion Tour Finale at Marquee nightclub in NYC.

Not only did he stay for T.I.’s performance at 12:30 a.m., but he stuck around while DJ Berrie spun music late into the night.

“He was definitely having fun with his boys,” says an onlooker. “He was one of the last people to leave the event.”

Maybe he didn’t know she was in the hospital, or had spoken to her and knew she was going to be released. Or maybe it was something else. But just to be safe, we’d recommend flowers or jewelry or a hit song, stat.

Montreal is about an hour away by plane, and Jermaine is totally loaded, so if it were a real health emergency, he could have been by Janet’s side fairly quickly – that is, if he had been notified. Janet stayed at the hospital for two hours and was released, which indicates that it couldn’t have been anything too serious. Then again, the singer did cancel two East coast dates to recuperate from whatever is making her sick, so who knows? Either way, I’d give Dupri the benefit of the doubt on this one- I’m going to guess that he didn’t know his girlfriend had fallen ill. Otherwise, I’m sure he would have canceled his boy’s night out.
