megan mullally sean hayes sean saves the world gi 'Sean Saves the World' sets 'Will & Grace' reunion with Megan Mullally guest appearanceBreak out the vodka: Jack and Karen are teaming back up.

Megan Mullally will appear alongside her former “Will & Grace” sidekick Sean Hayes in a future episode of his freshman NBC sitcom “Sean Saves the World,” TVLine reports.

While Jack and Karen always seemed like siblings, this time around, Hayes and Mullally will actually play related, with the guest star attached to portray the sister of Hayes’ character in the 17th episode of the season, due to shoot in early February.

This will be the first time the two have appeared onscreen together since “Will & Grace” left airwaves in 2006.

“Sean Saves the World” hasn’t exactly been a hit for NBC, but the newbie series was recently picked up for an additional five episodes, bringing its Season 1 total up to 18.

“Sean Saves the World” airs Thursdays at 9 p.m. ET on NBC.
