Brad Pitt got some early parenting practice for his future brood of six, by playing with Tom Cruise's daughter ISABELLA on the set of their 1994 movie Interview With the Vampire.
Cruise claims he knew Pitt was destined to have a big family, because he had a natural rapport with Isabella, then just one year old.
The Top Gun star tells People, "Every time Bella was on the set you could just tell he wanted to be a father."
Pitt now has three biological children and three adopted kids with partner Angelina Jolie.
