The Blake Shelton Easter Egg That Connects These 5 Hallmark Christmas Movies

"It's funny how going back/ Can get you back where you belong/ It's the difference in just a melody/ And my favorite Christmas song," sings Blake Shelton and his mother, Dorothy Shackleford, in their 2012 duet, "Time for Me to Come Home." This lyric inspired five original Hallmark movies but was first turned into a novel by Shelton's mother (and co-authored by Travish Thrasher) in 2013, per Amazon.

"We had no idea [the song] was going to end up turning into a book deal for my mom," explained Blake Shelton via Just Jared. "Then from the book, it became basically this series of movies. It's amazing what they're able to do over there, but it's been a cool experience to have that with my mom."

Country music star Tenille Townes — who plays herself in "Time for Him to Come Home for Christmas" — backtracks Elizabeth and Josh's love story with an energetic rendition of the 2012 duet. It's a musical "Easter egg," paying homage to the lyrics that started it all. As noted by star Tyler Hynes in an interview with TV Fanatic, "... the fact that Blake Shelton is involved and he's managed to bring in someone like Tenille who is unbelievably talented, she gives an absolutely lovely performance at the end of our movie singing ["Time for Me to Come Home for Christmas"]."
