NBC’s revival of “Will & Grace” has booked Molly Shannon for a guest starring role in the back half of its first season, Variety has learned exclusively.

Shannon will be reprising her role of Val Bassett, which she originated in a 1999 episode of the Peacock’s hit sitcom’s original run. Val was a neighbor of the titular Will (Eric McCormack) and Grace (Debra Messing) who memorably acted as a replacement best friend for Will when Grace was too busy with work and later went on to stalk Jack after seeing his one-man show. Shannon appeared in five episodes from 1999 to 2004.

Shannon is the latest returning favorite to pop into the revival. Others who have already appeared in early episodes include Harry Connick Jr., Michael Angarano and Leslie Jordan. Minnie Driver and Bobby Cannavale are also set to reprise roles later this season.

“Will & Grace” is currently averaging 2.1 rating in adults 18-49 and 7.5 million viewers per episode, making it currently NBC’s second highest-rated show behind “This Is Us.” The show airs on NBC Thursdays at 9 p.m. and has already been renewed for a 13-episode second season, as well.
