Debra Messing excitedly announced via Twitter on Tuesday that a Will & Grace reunion of sorts will take place on her new show, The Mysteries of Laura. Messing starred opposite Eric McCormack in Will & Grace for eight years. McCormack’s upcoming guest appearance on The Mysteries of Laura will mark the first time the two have worked together since the end of Will & Grace–back in 2006.

Messing stars as Detective Laura Diamond in the new series. Her character is a homicide detective with the NYPD. She faces a slew of additional challenges in her personal life since her ex-husband (played by Josh Lucas) is now her boss on the police force, and she must balance work along with raising their young twin sons.

Deadline reports that Eric McCormack will appear on The Mysteries of Laura in the role of Dr. Andrew Devlin–a heart surgeon who is suspected of homicide following the death of his ex-wife. To add fuel to the proverbial fire, Devlin and Diamond were once engaged. Deadline adds that “sparks will fly.”

Debra Messing retweeted the exciting news after Eric McCormack first shared it on Twitter.
