Jack, 27, took the cute picture of Lisa holding Pearl in her arms yesterday before posting it to Twitter for his fans to see.
Alongside it, he commented: "I love my ladies. :-)"
Lisa is wearing a simple black vest top in the sweet snap, while 15-month-old Pearl is dressed in a cute sky blue frock with white polkadots.
Speaking recently about fatherhood, Jack admitted: "Getting married and having a child definitely has focused me."
He also joked: "Now I'm not so much worried about going out on a Tuesday night and staying up until 3 in the morning and meeting hot chicks."
