Jones stars alongside Tennant in new drama Single Father and explained that she loved working with him.
"Obviously Doctor Who was massive so I was really excited about meeting David," she told the Radio Times. "He's the funniest, most charismatic, intelligent, humble actor."
Jones also revealed details of the show, saying: "[Tennant] plays Dave, recently widowed and struggling to bring up his children, while I play his widow's best friend. We're brought together by grief, and emotions get complicated.
"What I love about the drama is that it asks: how would you react in that situation? It's wonderfully grown-up and it feels authentic."
Single Father is expected to air on BBC One in October.
