The actress, who joins the village in the role of Megan Macey tonight (February 21), expressed her excitement at being part of the programme in time for October's milestone.
Faye previously missed out on Coronation Street's 40th birthday by just over a year, as she finished playing Judy Mallett on the cobbles in late 1999.
"I missed out on the Corrie one - so I'm going to do the Emmerdale one! That will be fantastic," Faye told Lorraine today.
She added: "They've got some brilliant things planned."
Faye also said that she is delighted by the warm welcome she has received from Emmerdale's regulars since she began filming.
"They're so lovely, it's so nice," she explained. "Everybody's been so kind to me. They've shown me down the corridors. Because all the studios are different, I'm often found wandering down the corridors!
"They've been really, really lovely. I know it's a cliché and everyone says that it's like one big family, but it really is."
Emmerdale celebrates its 40th anniversary on October 16.
