Jennifer Knight (Challen Cates)Loving and kind, Jennifer Knight (Challen Cates) is Kendall and Katie's mother. She lives in the Palm Woods Hotel with her children. Since none of the other moms relocated from Minnesota to Los Angeles, Jennifer is the de facto mom to all the boys in Big Time Rush. She gets along very well with Katie, Kendall and the rest of the band but she is not afraid to be strict when necessary.
