"Things expand this season," Messing told ET. "You know, we really get into each character's private lives. Grace gets a boyfriend. Boom. That's right. And I'm not allowed to tell you who, but you're gonna be so excited."
The 49-year-old actress said her character's boyfriend will appear in the beginning of the season, but not the first episode.
"All I'm going to say is that is one of the big things that happened," she noted. "You know, we're gonna do what we always do, which is comment on what's happening in the world right now and, you know, try and make you laugh out loud on your couch for a half hour every week because you know that's what we wanna do -- we wanna bring that joy."
Clearly, Will & Grace's big revival has been a success. The show is currently up for five Emmys, including Megan Mullally for Outstanding Supporting Actress in a Comedy Series. In March, the show also got renewed for a third season.
