Dupri -- So So Insensitive?

Janet Jackson's quick trip to the hospital was not going to get in the way of Jermaine Dupri's night.

The R&B impresario hit up Patron's Music In Motion Tour Party at Marquee in New York City last night. Spies inside tell us he partied it up with friends, caught a T.I. performance, and didn't leave until 1:30 AM.

Hope he sent flowers.
