WATCH: Khloé K’s baby True only smiles for Tristan – and it drives her mad

Los Angeles - Khloé Kardashian has admitted she feels rather put out that three-month-old True only smiles for her daddy, Tristan Thompson (27).

The Keeping Up with the Kardashians star (34) says she refuses to FaceTime her tiny tot when she's away because True won't laugh or even crack a smile – but she’ll happily giggle and gurgle for her NBA star dad.
