In the two-hour Sister Wives episode “Groomzilla,” daughter #5 Mykelti, her moms and her fiancé, Tony, go wedding dress shopping. Who knew Tony would be so opinionated about the dress? (Maybe they should’ve gone on Say Yes to the Dress!) Anyway, when Mykelti asked her mother Christine (wife #3) to sing at their wedding, Christine initially said no because she thought Mykelti was kidding. Christine admits that she has a nice voice but thinks it’s not amazing. But when Christine realized her daughter was serious she agreed, and is now taking singing lessons to prepare.
Christine will sing the song “Let Me Call You Sweetheart,” which her grandfather used to sing to her grandmother, to woo her. While Christine did not approve of Mykelti marrying Tony at first (she and Kody thought they needed more time to get to know each other), Christine says she approves now. And she’s singing at their wedding to show Mykelti that she supports the two of them together as a couple. “This is a big deal,” says Christine, “And I’m way out of my comfort zone.” Sister Wives airs Sundays at 8pm on TLC. It’s followed by Seeking Sister Wife at 10pm. [Related: Sister Wives: Mykelti and Tony Wedding Guests Threw Frisbees]
