A “Will & Grace” alum who is still busy working for NBC just added another gig to his list of assignments, Deadline.com reports.

Sean Hayes, the Emmy winner who played Jack on “Will & Grace,” will do a multiple-episode arc on NBC’s sophonmore drama series “Smash.”

The story reports: “He will play Terrence Falls, a comedic television and film star who is making his Broadway debut in the musical ‘Liaisons,’ based on the novel ‘Les Liaisons Dangereuses.’ Due to a series of comic circumstances, he becomes a major thorn in the side for Ivy Lynn (Megan Hilty) and other characters.”

Hayes is also executive producing the NBC drama series “Grimm,” and will be playing Ava’s (Maya Rudolph) former accompanist in a multiple-episode arc during the second season of NBC’s “Up All Night,” the report notes.

Hayes won an Emmy in 2000 for “Will & Grace” and was nominated a total of seven times for the role.
