We first heard buzz about the possibility earlier this week. E! News was reporting that Moore would appear on the show. And Alec Baldwin himself even said, "I won't say who it is, but someone very near to us who may be coming on to play my girlfriend for four episodes."
Julianne's rep would give up any deets, saying, "You would need to contact NBC for an official answer.”
But now we have proof! Just yesterday, Julianne and Alec were spotted filming in New York! An eyewitness tells E!, "I saw them right around 3 o'clock. To be honest, I can't remember what they were wearing (too distracted by how pretty Julianne was), and during the time I saw them they were in between takes, so not really saying anything of note. They looked verrrrry chummy though! No one else from the cast appeared to be there."
So get ready to see Jack Donaghy’s soft side again!
